It was a 90 degree day in Ohio but it was comfortable
operating from the truck with the air conditioning running.
I arrived near the 4 corner grid square boundary near Burbank
Ohio just before a 3 degree AO-7 pass. I set up in EN91 but
was only able to hear DG1EA. The horizon was a little
It looks quite cool. Have you tested it with an arrow to show it can handle

Jim is about 20 miles away from the DM51/52 line and plans
to operate from there on the AO-27 pass coming up at 2047z
or so. If he doesn't make that pass, he'll likely be on FO-29
at 2213z or so. You can track him on APRS, ND9M-9.

I hope a few USA and Canadian hams from Wisconsin to North Carolina will wake
up early and give me a call on AO-7

Yep, will be just south of Shelter Cove on Chemise Mountain. I'm
looking forward to it - this area will be a new one for me!

Thanks for all the feedback on the tracker. A few people commented that it
was a bit complex mechanically. This got me thinking about a minimal version
where the mechanical section could be built in less than an hour by almost
anyone.
Several people asked about moving antennas. The motor in the
Hello all, whats the take on these antennas? I am sure someone on here has used
them and they certainly look cool but how do they perform?
Dont you have to switch polerization on a cross polerized yagi?
I know there is not a perfect antenna, just wondering about the Helicoil...

What, exactly, is a helicoil antenna?

A Helicoil is a threaded insert used to repair stripped threads.
I think you're asking about a HELICAL antenna.
They work very well, and are easy to build. They're very forgiving in
construction errors, but have a few pitfalls you want to watch out for.
You do NOT want to wind one on PVC pipe
I second Jim's assessment here. Helical antennas are the only way I will build
an antenna at 1.2 ghz or higher. It's not worth the stress trying to measure
things to the precision needed for a Yagi at those frequencies. The less
stress (and time) taken to build the antenna, the more
satellite program!

Twas just a joke ... But YOU knew that ... (grin)
There is an amazing gentleman out in the Palm Desert area ... met him at the

for sat work.
But they're only about $100 ...

Hello Kevin-I have built a few of these antennas over the years. Mostly for
1.2ghz RHCP tx and 2.4ghz LHCP rx for a dish feed. As mentioned the
polarization is fixed. The helix antenna is pretty broad banded. I never
built one for 70cm or 2m however I have been tempted. Here it
