I built one of these at a local ham club meeting. They talked about it being great for fox hunts, but nobody mentioned you could use it with an HT to hit a repeater 60 miles away!

Thank you for sharing your knowledge and expertise with your videos. I’m just getting back into amateur radio and the new technology and information that is available is staggering and somewhat overwhelming at times. I find your videos to be clear, concise and welcoming to those of us who are new to this great hobby. Living in an apartment building makes antennae’s somewhat challenging as I have to be rather stealthy with them. Most of my activity ( when I’m licensed in the new year ) will be field transmitting and I’m gathering various radios and antenna styles to experiment with. I’m really looking forward to using my QRP radios as well as my stronger radios under field conditions. 73 John in Toronto Canada. 😀

Great Ham Radio project Michael. Excellent easy to understand video. Especially like the method you use to speed up the construction portions of the project. It is refreshing for a ham to give the parts lists and step by step instructions. FIRST CLASS PRESENTATION. Very professional, I thought you must be a teacher with many years of experience. I built two of the antennas for an upcoming ham club fox hunting event. No problems, worked just as you said and showed in your video. Other Amateur Radio operators could learn many good tips and methods to present and do videos on ham radio projects if they watched your videos. Keep up the good work Michael. Great Job!

I never was a professional teacher, but I did stay at a Holiday Inn Express once :).

Just made contact with the ISS via APRS using this tape measure antenna and my Yaesu FTM400XDR. Thank you for posting this video Michael! 73s from KI5BWY.

A friend of mine built one of these. This is only based on a test of one antenna. I measured performance in a clear open area. Since the intended use was hidden transmitter hunting, my only concern was the antenna pattern. I found two important things with the antenna brought to me: 1.) It had terrible common mode on the coax. I could touch the VNA analyzer case, or slide my hand along the coax, and see a fairly large change in impedance. 2.) It had generally poor directivity in the 2M Ham band. It lacked a good deep null off the rear. It actually seemed to have better directivity on the weather band than2 meters. I did two things. 1.) I altered the spacing. We just swapped the director and reflector around on spacing so the reflector is wider spacing like almost all 3 element Yagis are. This improved the back null quite a bit. I made no efforts to trim elements, but suggested he make the elements slightly long in a future model so we could trim them in. 2.) I grounded the coax shield to the center point of the reflector. We had about 18 inches of coax spiraled around the boom to the hairpin match. This forms a high impedance on the shield at the hairpin. This completely eliminated the noticeable SWR changes as I moved my hands along the coax.

Just finished building this antenna and it is amazing. Thanks for putting this video together. Made a few contacts over 50 miles away with an HT.

Never thought about using tape measure as an element. Great idea.

I love your videos. You make them understandable! I’m working on my antenna now. I used plastidip on the ends to prevent cuts. 73 and thank you!

I built one of these over the weekend and it works very well. I got the SWRs down to 1.1:1 and instead of soldering the coax to the driven elements, I decided to use an SO-239 connector with 3 inches of wire for the center conductor and ground, each. My house is in a 100 ft valley (compared to surrounding terrain) and I am still able to talk to my brother 4 miles away on 1 watt of power. Also, I'm using RG-8X coax to connect to the antenna.

This is a very informative and clear video. I built this antenna with one minor modification -- instead of soldering coax directly to the feed point, I instead soldered an N-type socket, and use an N-type to SMA cable to connect to my HT. (I have bad luck when it comes to stripping and separating coax. My approach ain't pretty, but it works.) I also covered the tips (last 1/2 inch) of the elements with electrical tape to avoid cuts and scratches. Analysis with a NanoVNA showed my version had an impedance of 52 Ohms and minimum SWR of 1.1:1 at 148.5 MHz. The SWR increases rapidly from that minimum, but still seems reasonable within the 2-m amateur band. On 70 cm, the antenna has an SWR of 1.6:1 at 449 MHz. I'll try playing around with the spacing of the driven elements to see if I can bring the resonant frequency/ies into the right range.

I built this antenna today per your instructions and it turned out amazing! Thank you for the clear and concise video. 73, KF0OVB

Michael, I watched this a couple times last night (friday.) I managed to copy a rough idea of this (2 meter, tuned with the nano) and made a contact 52 miles away with a UV5R, yes you heard that right, a little 3 watt radio. I think the real lesson here can bring up a multitude of topics which I will discuss with some other people soon here: hams have the privilege of building their own stuff, our signals can travel much farther, that topic of possible interference could possibly happen if it's zipping around the earth or bouncing off of things and lastly and most importantly never underestimate the ability of underrated equipment in the right conditions. I really think this was dumb luck but I did use a Google distance calculator, a compass bearing and found a good spot. Thanks for all you are doing with this channel and being a servant to others. The information you taught might save somebody else's life one day.

Glad to hear the antenna is working well for you. I mentioned 10 feet of PVC in the parts list as that's the length you usually but the tubing at the home improvement store. But really any amount of scrap tubing will work, it doesn't have to be a certain thickness or diameter.

Very clear - thank you! Project for this weekend 😎🙏

Very good video, the pace was great. Simple down and dirty Yagi and you could easily add a couple more elements for 9db of gain.

Great idea, I will make mine soon! Thanks!!

I just built this and it looks like I am hitting towers about 50 miles away. However, please tape up the ends of the tape measure, my ten year old son was holding the antenna while I taped the cable and he dropped it on my leg, And it cut an inch and half gash, I am headed to the clinic now to see if it needs stiches.

Enjoy your videos. Great stuff.

I'm going to try this one. Looks like a fun project to get started with.

Awesome work. 👍

Great video and idea, thanks for sharing, super cool. stay safe and 73's

Great video by the way, looks fun to build!

Your build is very similar to the way I typically make them. I like to dip the ends of each element in that liquid plastic stuff they sell at hardware store for coating tool handles. It makes the ends more visible and prevents the ends from scratching or poking anyone. Also, I always put a cross on the director end as well. Once you’re close to a hidden transmitter, it’s often easier to zero in on the location using the null on the reflector end, so the extra cross allows you to hold the antenna ‘backwards’.

Very helpful video and easy to make.

Really very well done! Thank you, Will make one, KM6IKH, 73...

Built one today. I don't have the means for tuning so i just measured and assembled it as precisely as i could. I was able to receive voice from AO-92 (VHF downlink) and SO-50 (UHF down) loud and clear. However, it is not a magic wand! and I was NOT able to transmit successfully to a friend 1 mile away through medium dense forest/trees (this is not surprising). Without so many trees blocking, I was loud and clear TXing at 4 watts from 1 mile. Don't expect to beat the laws of physics or anything with this, but even without tuning you'll be able to recieve MUCH better than you might with the rubber ducky. Tune it for best possible TX capability! Thanks VBR for the awesome design! de N0CALL ;)

They shouldn’t have cost that much. Harbor Frieght tape measures are cheap and work great.

This looks like a fun project for when I get home. Thank you!! Just found your videos and they are very informative and easy to follow. One question is what stand did you use to hold up the Yagi at the end of the video?

Neat trick I learned for cutting the tape measure: you don't need any tools at all! If you fold the tape back on itself inwards (numbers touching numbers), and then press the fold flat to make a crease, it will snap and leave you with a perfectly straight line! Unfortunately, I learned this too late to save myself from a half-hour long battle with my dremel (most of it searching for the pieces).

W4CEC here......I am building a couple of these for the Legion Club, WF4TAL. I think this is fun!

You build the antenna yourself to learn how antennas work (and save money in the process). That is what this is about. Those who buy "off the shelf" really do not learn anything regarding Amateur Radio, only create excessive cost and no knowledge regarding antennas as a whole. We can try to build our transceivers and do a pretty good job of it, but those who build antennas really know radio.

Thanks for the wonderful, clear, concise video! I'd like to make one of these to attempt voice contact with the ISS from my Baofeng handheld - talking to space on a shoestring, if you will. I will be transmitting on 144.49 MHz. Would I need to make any changes to the measurements outlined in your video, or do I just need to find an SWR meter and "tune" to 144.49 by adjusting the driven element gap? Thanks again!

UPDATE: Picked up a MicroFox (15mw output) and built a couple of these using an active offset attenuator. I use them specifically to teach scouts for Merit Badge Requirement #9, partake in ARDF, but I also use it as a DEMO for a variety of youth events. I set the FOX a distance away, and show them how to use the setup. My attenuator offsets the main frequency by 4MHz, making it cleaner to find the fox. The original antennas still work, but I am building a couple more so multiple sets of Scouts can look at the same time. I also have a few full power HTs (6watt) that are crossband I have used for a greater distance fox hunt. However, this is still, as far as I am considered, the gold standard for the homebrew Yagi. It is simple, it is cheap, and it is fast to assemble. I used my NanoVNA and tuned it to 1.2:1 on 2Meter, and it was also 1.8:1 on 70cm I use it to contact the ISS Repeater and have had a QSO from FMo5 to EM26 through the ISS Repeater. NOW THAT WAS COOL!!! Thanks, Chris Cancilla de W4CEC

After following your instructions it works great! Any plans to put out a video on building a 70cm Yagi?

I like how you you use one tape measure to measure the other tape measure.

Great video! By changing the gap you would change the distance between the elements but leave the length of wire the same length ?

SUPER ANTENNA SUPER VIDEO

Nice.. (Slick Idea) I Will build one for sure.. I just need to be sure I Don't cut up the Wrong Tape Measure. Thanks for this TTYL 73s

Michael thanks for the outstanding instruction. I plan on building this for SOTA activations. Do you think you could repeatedly roll this up in a Fly rod case for strapping to a backpack?

Love this antenna idea! Any thoughts on making a 70cm version? Or making this a dual bander by putting 70cm 90° off from the 2m elements?

Great video! Best one I have seen on making a hand held Yagi Beam Antenna. 73

These DIY antennas are great for qrp camping or for use in direction finding fox hunts

If you make a 3 element yagi and tune for the greatest gain, ignoring swr and f-b/f-s ratios, it might be possible to achieve 7.2 dbd gain, but if you strive for good balance in all those parameters, then 5-6 dbd gain is all you can hope for!

@KB9VBRAntennas

7 жыл бұрын

You are correct. Since this antenna is designed for fox hunting, it's been optimized for a high front to back ratio, hence the higher gain and deep nulls to the sides. But a more 'balanced' antenna would have a little lower gain.

Passed the wind load test too!

Wow, great! Could you use an antenna as such to transmit sound non-stop to a receiver 15 miles further in an attic? Or would you run into trouble as you are interfering within that frequency and other transmitters? :) I'm looking for a DIY way to have a live broadcast from one point to another 15 miles further, without making a radio (only one place needs to receive it) but it's been quite difficult.. :)

What an awesome yagi, but i noticed toward end of video how the tape measure fluttered in the wind/breeze! Would this affect it's performance? Cheers! VBQ543 Mick

I like this design!. Do you know if painting the whole thing would ruin any of its characteristics?

Just learning about this hobby. Few questions... Can the antenna be painted or would that disrupt/muffle the signal in any way? Also for "tuning" the gap between the tapes could you solder a nut onto it and use a bolt to easily and quickly adjust the distance between them? The further you thread it in the smaller the gap.

Hi Michael, I love this antenna design, and im looking at building it. One question, I want to add 2 directors to it. What would be the final measurements?

Question: Would it affect the reception at all to coat the tape measure in plasti dip or rubberized undercoating? I dont see why it would but I wanted to ask to be sure. Id love to build something like this by cutting up and repurposing the old UHF TV antenna on the roof of my house.
