Cool antenna(s)! Using the Golf bag.....brilliant!

Thanks for the review. I’m thinking of buying it and you helped me a lot.

Imagine the performance when you add a little bit of whipgrease! Thanks Hosh, I saw this antenna and was wondering about it.

What a great idea! Another antenna system to pursue in my search for the best portable antenna. Thanks!

Great video !

I love the cap you're wearing.

That’s awesome 👏

Nice video! I have two of these MFJ 2104's. I use one for FD and the other one for my home station setup. Also I have double original "Larson" ham sticks for each band 6 through 80 meters. I mount these (at home) at 30 ft on a telescoping mast. I have 4 bands being mounted. The results have been fabulous! Out does my Hustler 6BTV vertical a mile 20 radials on the vertical! 73 K8ESE

In 1981 I built a 6 band Octopus out of electical boxes and rewound Firestick cb antenna's. My first contact was on 15m with an AH2 in Guam.

Great new twist on a very old idea. My elmer had a multi leg antenna at about 20 feet that worked well. It is in the ARRL antenna book. For those without trees this is great!

It is interesting that I was watching your review of the Shark Ham Sticks on The Chameleon Spider and Quad Dipole Ham Radio Antenna video that you made February of 2022 showing the "made in America" Shark version of this system, when this video cam up in my recommended list.

You could use Hamsticks for the higher frequency bands but for 80m or 40m run a wire dipole using pl259 connectors from a set of the ports for a more efficient inverted V antenna.

Golf bag antenna caddy, cool!

Me: camera bag for my gear. You: golf bag for the antenna. love it de w0vet

Interesting option.

Could you do a video for new hams covering in simple terms when baluns and ununs are used and how to know when 9:1, 49:1 are necessary etc. You put out great videos!

Golf bag was a great idea

What's the transmit efficiency of the ham stick dipole? I've heard that ham sticks are really inefficient below 20m making your ERP more like QRP.

Would this work well for a base antenna? Thinking it might be worth getting and mounting to the roof

Whats funny about this is, a guy who I had talked to because I had questions, designed and built this some years before MFJ even thought about this using a metal J-Box and the proper connectors, and I mean years before. And this design has been suggested for HOA type situations well before MFJ. Oh well.

I'm wondering how this antenna would compare in performance with a wire dipole. Any comparison?

Dear Dr. Josh, thank you for this. It is 3 years down the road, from when you made this video. For me, After long hours researching antennas, radios, coax, etc., I am preparing to get my first HF rig. We live in the country, no HOA. There are lots of trees, and 50’ of coax will not get me above them. No $$$ for a decent 50’ antenna mast, either. There is SO MUCH TO LEARN, but, I just want to get started - I can improve my rig down the road. For now, something that IS (potentially) portable, (although it will likely stay in our yard 99% of the time) like this may help me get out on 10m, 12m, 20, and maybe 40m. It is understood that you are very busy. Would YOU use this for your base station antenna?

Will this work on the FT8 area of 80m??

I have a 60 foot tower. now I know what to attach to it. so it's 1 antenna for each band correct?

Lol. That was funny

What would happen if you installed 2 or more pairs of hamsticks of the same frequency (e.g. 20 meters). Would you then get a multi-directional dipole to save you having to rotate the it ? Just thinking of a limited attic space application where you could have two oriented east/west and two oriented north south

I assume it would take on really weird lobes that would be hard to judge the pattern on.

Thanks. I don't have the Octopus.. but I do have the MFJ-347 dipole mount. Do you recommend any sort of balun on this.. or, simply attach the coax and you're done?

Ham sticks are just one unbroken wire really. Half of the ham sticks connect to the negative. The other half to the positive.

Great video demonstration. I have a corny question. What would or could you use all 4 radial ( dipoles) for the same frequency, co-phasing/quad phasing ???. Would doing so create a friggen mess, how would the radiation pattern work, or would it?. Thanks for sharing!.

The Octopus will be more wind resistant as its balanced. As you noticed, aside from initial tuning there is little additional work you have to do on different bands. In either case though, I recommend staking the antenna down and better guying it if you're going to be in wind at QartzFest.

The big ears I suspect would have better transmit results due to the elements being longer and closer to actual wavelength?? The octopus being called a rotatable dipole,,, at the height of most portable masts does rotating actually make any difference??Usually dipoles that are to close to the ground are omni directional. They do look great for portable ops.

HELP!!! Anybody have issued with getting 40 meter sticks set up? I tried for over an hour and then went all the way IN as well as all the way OUT with the whip and then worked from both ends down an inch ar a time but the best SWR I could get around 7.175 was 4.7:1. I tried a few nore adjustments and finally gave up with it setting at 5.6:1. It really seemed to want to stay around the 6.8 Mhz area and could get it to give me a 2.1:1 there but nothing better ANYWHERE else with any adjustments. YES, I am using the 40 eter sticks, or at least that is what the bag and sticker say. I am using an MFJ Analyzer as well. I had no issues gettng the 80 meter to give me 1.2:1 at 3.8Mhz

And the problem I always wonder is with a tripod, you almost will never able to get antenna high enough for the lower band. So how is the TOA on this?
