I own the Cirro Mazzoni midi loop.. its quite an amazing antenna for its size 2M.. my first contact on 40M was Melbourne Australia with just 50 watts!!

Thanks Josh! Nice antenna. You have inspired me to play with WSPR!

II have been using my CHA F Mag Loop for over 4 years now as my main antenna. It is set up indoors in my dinning room and hooked to my FT- 817nd 5 watt max. QRP rig. I use the solid aluminum big loop most of the time on 60 through 10 meters. CW is my main interest but I use SSB and PSK31 and JS8call some of the time also. I am on it every day either indoors or for my POTA activations in the field here in S. W. Utah.. I am a long time QRPer and even get down in the milliwatt output range. I must say, I have never had so much fun with the challenge of QRP as I have with this loop. One thing that was not mentioned is how by directional this antenna is even when operating from indoors This is a very directional antenna and it brings other stations out of the mud or can null unwanted interference noise. I’m anxiously waiting for 10 meters to open up. De WA6YPE 73

Great info about the use of beacons and digital modes to evaluate where your signal is reaching, and help with voice modes.

All I can say is wow. That is an awesome portable antenna. Well done on the review showing the options and hands on assembly!!! Thank you!! I may have to get one of these down the road!!!

I want one. The ease of set-up, not needing radials and the ability to do not.only DX but NIVIS with the same antenna, without any major adjustments intrigues me. My concept of operation is to keep my station highly mobile, simple but still effective, all why keeping near QRP levels of power usage and power consumption. I'm saving up for one now. Thanks for posting this review

Such a great explanation - much appreciated!

Great Video, Good Timing, Just bought a KX3, looks like a Loop is the way to go for Portable use, Great Winter Project 73's

Great summary! I need to get out more with mine to get better accustomed to using it, my only gripe being that it can be really finicky when it comes to getting the tuning knob just right. The high-power adaptor actually lists max output on SSB as 60W and I have had no problem pushing out at least 50W. I would think that at least on the higher bands that it will probably outperform most compromise antennas on 100W output and would rate it as more than simply a QRP setup.

Thanks...allways fun and informativ 2 se your videos... stay safe and have fun

Nice review and I have one for some of my portable opps with my Kx2 where a full size antenna will not work of fit. I like the power compensator to use when I have more power.

Great video as always. I'm limited on space AND live in an HOA in Hawaii, but unlike comments below, no success. Running a Yaesu FT-891 and did the "no look" tuning @14:10. Good SWR, heard VE7TBN and ZL3XZ, but no contact.

magnetic loops have been there for ages. They are a decent compromise for those who do not have the possibility to set up a larger antenna. While efficiency is marginal, for receiving they provide good directivity and thus good S/N. On transmitting any vertical will greatly outperform a loop. Magnetic loops are very easy and very cheap to build. With a fraction of what the Chameleon costs you build one as good as this and with a motor, which let you tune it remotely. Ham radio operators used to learn how to build the basic stuff they needed. Nowadays ham radio's main equipment seems to be the credit card!

Hey Josh yeah I'm just getting back in the radio again I was bored for a long time but trying to check out antennas I just don't feel like building one I like to just buy one and put it up but that definite looks impressive I'm just watching the video now and I'll give you my opinion in another comment after it's over it looks pretty interesting thanks for sharing it 👍

After 60 years in ham radio I could On my extended lot in Florida.-- On my 70 foot crank up tower were the strong 15 foot mask going upward above, I had 3 high Gain yagis five elements on 20 ,15 meters had five elements and so did the 10m yagi. On a 70 foot tower separately I had a full size 40m two element quad with 30 meters wrapped inside two elements and then three elements on the 2 other warc bands. I had a 50 foot tower with various to meter gang Yagi. For 80 meters I installed two high gain high towers 130 feet apart and use the matching network which from the shack I could switch either bip or bop--- with part of that antenna on Japan or the other part on Europe switchable from inside the shack. All operated with everything from 800 to a kW output. Now I'm tuning into youtubes and seeing single element loop type antennas there are useful for portable or for using that condemnable FT8. And since I moved away from most of those other antennas I still have the Christmas tree but I realized looking at KZread that FT8 and the simple loop type antenna, low power, is saving him radio for all the hams that are penalizes from putting up big antennas and from running a kilowatt amplifier. So I guess FT8 and these little loops are saving ham radio and for that I say thank goodness.

Très intéressant et encore merci pour cette super vidéo.

Might have to invest in one. Just got a IC-705 a couple of weeks ago and an end fed antenna to work HF with. Had some luck on 20m and 40m without using a tuner. Haven't done any weak digital signal modes yet, but plan on getting into trying some soon.

I'm not only getting back into the ham arena and I also decided to go with a loop hopefully I'll be able to figure it out.

As Always, thanks for your well done and informative videos. You have a very natural presence in front of the video camera. I have the F-Loop too, but with the two part metal out loop. It works well. I do agree with those who believe that SSB test are better. After all, who talks on FT8 (no talking) or on WSPR (also no talking). I once hit Antarctica with WSPR, but I was not able work work them a second later on SSB. I tried. So WSPR propagation say nothing about SSB propagation. Also if 'it WSPR goes out further' then again that's proof that SSB does not coincide with WSPR. WSPR is more fun than that dreaded ft8, which I can't pretend hard enough is radio. Again, thanks for the video. 73 from N2LRB

Thank you for the comment and kind words. The point of wspr is that you can see what paths are open, including SSB. It’s a fantastic mode for knowing when voice contacts are possible.

Great video, possibly the most complete (and steady-paced) step-by-step video on this loop that I've seen to date. *** Most of my use is with the loop indoors (HOA) I run the coax from the loop into an A/B switch box with "A" going to the rig and "B" to a antenna analyzer, which I put at the base of my tripod. This configuration allows me to adjust the loop while looking down at the analyzer. Once I get the best SWR I just switch to "A" and I'm ready to transmit. *** Recently I replaced my main station (TS-2000) with an Icom 7300 and I discovered that I could get very close to the correct SWR zone by watching the 7300's spectrum scope (it looks like a 'wave', which gets larger as the capacitor is tuned to the correct frequency. Too much one way or the other (right or left turn) and the wave decreases moving off to one side of the frequency or the other.. My hearing isn't as good as it used to be, so the visual indication on 7300 really helps (I imagine the 705 would be the same) *** Nice bag. I wish they (Chameleon) was more consistent with the bag they send out though (the F-Loop I bought this Spring came with a tiny 14" x 9" bag that barely allows everything to fit in it). *** What I'd really like to see as a followup video is where you test the loop with the CHA POWER COMPENSATOR (which I believe is just a door knob capacitor) and verify once and for all that it really gives you a good increase in the radiated power output (i.e.- "I talked to Bob and he said I'm 5/6 but when I added the Compensator it jumped to 5/9"). I've never seen a video where someone actually does an A/B test between stock loop and loop w/compensator doing a real world test like that. When someone DOES do a video with the Compensator it's never clear if it deflects most of the higher watts coming from the rig (with only a minimal increase coming out of the loop), or if the loop really uses everything the transceiver is putting out? 🤔 *** With the aluminum loop connected was your frequency spread the same (40-10) as with the coax, or did you loose a band at one end or the other? Also, was the bandwidth you saw the same as or better than with the standard coaxial loop? With the "booster" cable installed did you see a larger bandwidth on 40 or 20 meters, or was it just as narrow as with the stock loop? *** Once again: Great video....👍

“It has mounts for a tripod. And a hole.” Great video! This is my primary antenna since I live in an HOA and don’t want to be setting up my other antenna and tearing it down all the time. I leave it set up and just pop on. 73 K0VMX

👍👍👍👍👍 Thanks for a very thorough walk-through! I am a total newbie. Just ordered my very first SDR Bundle kit from RTL-SDR Blog. May I ask: 1. Would this work with RTL-SDR Blog v3 to receive HF in Direct sampling Q mode? 2. Perhaps there is something else more suiting for indoor apartment use? Once again, thanks.

Chameleon Antennas are top notch and I have owned this loop antenna for a couple of years now. I went through a hate/love (yes in that order) relationship with it though. The portability and ease of setup (reliably 5min) is spectacular. BUT it’s useless on SSB Tx. Anybody claiming anything else is likely strongly biased. Still, SSB Rx isn’t actually too bad and it’s very quiet. You will find that reviewers of this antenna tend to focus on digital to demonstrate its performance. Well the reason is that’s it’s the only thing it’s useful for. Just don’t be fooled to believe you will have many SSB QSO’s. Even if you do make the occasional contact, it’s way too unreliable to be trusted when it really matters. I performed extensive testing in various settings and distances and can confirm that I’m usually not being heard on SSB, even if I hear the other station well. I use the power compensator btw so I can almost double the power (SSB 50W/ Digital 20W) I was never able to get 80m to work well other than some Rx and no longer bother to make it work. I think promoting it as a 80m antenna is a bit of a stretch. Interestingly, the power compensator doesn’t seem to work on 80m. This all sounds horrible, right? Well once I accepted that it’s basically useless on SSB I started loving it for what it is. The small package and 5min setup to Tx/Rx a couple of digital messages is actually pretty cool. It’s high quality too and a pure joy to own. Customer service and support is stellar - I’m a fan and own some of their other antennas. So there you have it, it’s a great antenna in its own right but you will hate it if you expect it to be a performer on SSB. As it had been mentioned earlier by someone else, any vertical will outperform it on SSB. Great video!

Health and Safety aspects due to potentially high currents present at (especially) LF with magloops eg your XYL goes outside to hang the washing out while you are leaving it to do WSPR and she touches the non-rubber-booted PL259 assemblies to move it; minimum recommended distance between loop and operating position as a function of frequency (to avoid a permanent headache!)? etc. 3. Is there a (future) remote mechanical tuning option eg with a cable drive or motor drive for the case when you want it outside (eg your rv) while you are cosy inside so as to avoid constantly running in and out. Thanks again, Nick M1DDD

Very new and just exploring the ham radio hobby. I have a question. There seems to be 2 types (?) of communication styles? Active listening basically looks like actively tuning a bunch of static until you find a voice buried in static? Then Squelch listening where there are known channels that you stand by quietly until a transmission is made (CB,GMRS, FRS, 2m, 70cm?) This antenna is more designed for the static in voice style listening.

MPAS 2.0 is a great antenna, can handle 100 Watts and I've made several contacts from Ireland to South America on 20 Meters SSB @100 watts in the Summer 2020 in the Evenings and night UTC using just the single supplied counterpoise and the CAP HAT which I purchased separately. I do have a very low noise floor where I live too helping me hear lots of DX. It's also a fabulous SW receiving antenna, One thing that struck me is how quiet it is on receive compared to my wire antennas, I thought the Verticals were supposed to be noisier but the MPAS 2.0 is very quiet, again my area in the sticks is very quiet. The first night I set it up and heard a Brazilian station repeat my call, well, you can just imagine my face! I haven't used the wire antenna much but this would give much better performance on 160 and 80m but it still gets out well on FT8 on 80 and 160 on the vertical. It works so well I decided to leave it up all the time and take it down only for portable use, the exact opposite of what I bought it for but at least I'm making good use of it. I also have the excellent Super Antenna MP1, I even made a 1000 mile contact on 80m with the 80m Coil, but it can be a pain when band hopping going back and forth to adjust the coil, disconnecting the coax, hooking up to the analyser etc. The MPAS I can work several bands ( With the cap hat ) without a tuner. Get the MPAS 2.0, it can handle 100 Watts and it just works, every time.

@@o00scorpion00o I really appreciate your insight. Your comments confirm most of what I've heard/read regarding the MPAS 2.0. I live in the burbs, so I have space limitations that drive me towards verticles over wire dipoles. I'm running an ICOM 7300, so I'm thinking the MPAS would be a good fit for my needs along with the radio's internal tuner. Portability and field comms matter to me as well, so I much prefer a rig that can be quickly set up and taken down. My primary focus in HF is phone/voice contacts, but might look into the digital modes more closely next year when time permits. Good to know about the Super antenna. I looked at those as well and wasn't sure if all the adjusting/fiddling with it was worth it. Might take a second look. Thanks again!

I'm still waiting for Chameleon Antenna to build a "matcher" much like the "CHA-MIL Hybrid rated @500 watts" to handle a kilowatt - so, those of us working from an apartment with a balcony railing can run a decent amplifier on the lower HF bands.

I made a contact from SE Idaho to Japan on 18 meters. His window was open just long enough and the band faded. After years of owning it i could no longer remember which end of the unun was antenna or coax side and called. The guy on the phone was surprise to find out there was still a V1 out there still working and said very few were and that in the move they lost all the documentation and the original website data had been lost. My only option is to take it apart and check it out. But i'm thinking of just tossing up 124.5 feet of wire and making a 9:1 unun and calling it a day.

I know it is convenient and easy to run Whisper and present a flashy chart - but it is meaningless without explantion: You told us that the SNR would reveal if the connection was actual useful for a SSB QSO - yet you only showed the map with the contacts - but not annotated with the SNR - so I am not a bit viser regarding range for SSB Also, you briefly showd an effectiveness chart and then quickly closed it withhout explanation of the significance of the numbers. Does the 13% effectiveness with the Boost option mean I only get an effective 1.3W in the air when transmitting with 10W on 40m ?

I’m not sure why you say that. Of your report is 0 or higher, Ssb to that location is likely possible. Just need to look at the numbers.

Great video and I'm sure the antenna works very well but I feel it's too fiddly and to much tuning, everytime you move you have to retune , I live in the uk and this is not going to get used for 5 months of the year with winter weather high winds and rain I wouldn't want to keep running outside to tune even on a pleasant day , lot of money for what cannot be made a permanent fixture outside and to big to leave up in the house

I received my loop about a month ago (in the UK) and can confirm that it does indeed work well (indoors), I would go for it personally.

So how do you aim the thing?

Loops are directional off the ends, not broadside.

How can i order here from Philippines

Contact Chameleon Antenna. I'm pretty sure they ship anywhere in the world.

Do they have a 100 watt version? A 1500 watt version? Jeff N9NJN

Not yet but a 100W 10M to 40M is under testing/design.

Cool. Life is to short for QRP lol

So how many got F-d watching this? Not..and instead bought the antenna. 😂

So I suppose putting this up on your house roof is out of the question......unless you like climbing up and down the ladder?

How does it do for local use, (NVIS)?

I have not tried it specifically for NVIS, but I have made every close in contacts with it on 40 meters.

@@HamRadioCrashCourse Would I need to do anything different to operate NVIS? How low to the ground do you recommend keeping the antenna for normal operation and for NVIS? Thanks! W2QLH 73

I've used mine, checking-in on an 80m net, with Net control being 45mi away, and several 20-30mi distance 10m contacts with ease, but band conditions will always play a part in my success (or lack of).

Is that really LMR-400 coax?

Actually yes, the outer loops are lmr-400

All this stuff looks really fun. Must be nice to have a ham radio license. FCC is refusing to give me mine. I passed all three tests in April 2019. But FCC is keeping my FRN status "pending" because I checked the felony box. Yeah, I made a mistake in the past. I guess they're afraid I'm going to talk someone to death. At least I tried the legal route. I'm gonna start keying my ham radio down anyway with a fake call sign. Hey, I tried...

Josh, I need your help! I live in a condo on the second floor. I have a balcony that is 4x8, closed off on three sides. I bought a Super Antenna and I couldn't get out. 😔 Now I'm going to by a magnetic loop antenna but which one should I get? The Cha F-Loop or The Alpha Loop Antenna??? I hear Cha Antennas are a solid build but Alpha's say's it 100W.... Which one would you pick between the two? Please help, thanks in advance & you are the best ham radio channel on KZread yes even better than that guy in Texas hahaha.

Build it, great fun to do and the cost is minimal.

my mazzoni midi loop can handle 800 watts

This is a great antenna for QRP. Chameleon only makes great antennas. It is too steep for my budget.

If there is a giant power grid shutdown nationwide, will this prevent us from using the hams completely?

No. We’re not dependent on the grid. Just solar charge it my dude.

Guess you left out the very high Q on small loops at low Freq and the extremely low Bandwidth and huge phase shifts for SSB type signals that then sound terrible.

@arconeagain

Жыл бұрын

He literally says they are high Q and and have an extremely narrow bandwidth (when looking at and based on a representation of a typical SWR curve). What on earth are you talking about?

How can they be a resonant antenna? They're quite the opposite really, especially when considering they're designed to operate on such a broad frequency range in just one or two lengths. I'm a CBer and I know that (101 basics), like the rapper of that song. And you really shouldn't keep saying loop antennas, in reference to certain characteristics. The category of antennae is small loop. This is misleading for beginners when compared to an actual resonant loop.

One question: for my second-floor apartment, will this antenna meet all my HF DX needs if paired with my Ft-891 Yaesu?

@HamRadioCrashCourse

*All* your HF DX needs. Likely no, but someone in a limited space, like an apartment likely doesn't many other good options.
