i run a halo on 6M and squalo on 2M and have been really pleased with them for a number of years, if you stand them on end you can use them as a directional antenna, good vid Chuck!
I've seen those old pictures of mobile hams from the 1950's using the 6 meter round halo antennas mounted on the rear bumper with a brace in the middle.
Hi Chuck, great video! For years now I've been wanting to build a 2 meter quad, I built a 10/11 meter Quad about 30 years ago, quads are definitely my favorite antenna's. I like your design, it makes tuning a breeze compared to drilling holes through the boom, for the spreaders, Lol. Is it possible to get a link to the .STL files for the spreader hardware? It would sure save me a lot of time if I didn't have to reinvent the wheel. I'm just getting back into ham radio after being away due to deafness for 10 years, I sold all my equipment at that time, I now have a hearing implants and my hearing has been restored to a reasonable degree. So I'm back! I looked around for the .STL files with no luck. I would really appreciate a link to them, Thank you, Richard w6rch
Thanks, Chuck, been looking at these for a while. Think it would be great for portable operations when out I'm out on the bike, just need to work out some kind of portable mast.. Think it might be too heavy for the top of the 10m telescopic.. (hihi) 73
Kev. the 2m antenna is pretty light and you might get it to 20' on a 10m mast. Mine is aluminum if made from copper it might get heavy. Another option is make with aluminum arrow shafts , maybe make the corners with bent solid alum. that fits inside.
It appears to me that a "halo" antenna is simply a half-wave dipole that is distorted into a square shape. The principle of operation is the same as that of a half-wave dipole. But I imagine that its performance is compromised by its shape, and I would anticipate a degraded gain. Having said that, the polar diagram of the halo may have some advantage depending on the circumstances.
@@digitalanaloguehamradio The halo hears and talks to horizontally polarized stations in all directions. If you always use a Yagi, you will miss hearing signals in other directions. SSB, CW and FT8 VHF/UHF stations use horizontal polarization. Using a vertical antenna for those modes can cut your signal strength up to 30 dB.
Yes, on all bands. Operates the same as a fullwave loop, but measures like a half wave dipole. Put it round, or square, gets less noise, omni-directional, and is 50 ohms 😊. Super easy to build. Mine is a multi, just like a fan dipole. 40, 20, 17, 15, and 10. I could have used less wires and the tuner, but I prefer to be resonant. Works great
This antenna design has been around for over 40 years. Based on their application they work well. Nice job 👍 presenting the information.
I was just looking at these earlier this week but was torn between a Squalo and a halo. Still am. Thanks for the resources.

TeamReplay for the win! HLTW
Been kicking around the idea of making one of these for 6m. Very helpful.
Nice informative video, thank you for your time and effort

They are interesting antennas for sure, and perform really well.
Your tooo kind , thanks!

Interesting! I'd never seen this bad boy. Thanks Chuck!
Yes Jim they are pretty cool , my buddy says he talks to a lot of operators using them on 6 meters with good signals.
Just subscribed thanks for the information

What is the use case for this antenna I have got one
It is an omnidirectional horizontal polarized antenna used for weak signal VHF modes.
@@kp4md I have got one for 2 m thanks. I just don’t know how it’s useful. I was told it’s good for SSB 2m. With it facing upwards
Chris use it for 2m SSB it can help hearing stations and then use your yagi needed to pull weak stations.

What about 144 MHz Halo Antenna by Dr. Carol F. Milazzo, KP4MD
Really washed out. Did you grade this? Why the digital zoom back on each edit? A bit distracting. Good info though.
But can it be done with 20 meters?
I'm sure it could be done.
