and 2.4 out of the Grill instead, might that be better?

Hi Art,
I've got a BBQ Grill too, but used a 3 1/4 turn helix for a feed. I was
able to work AO-40 at apogee with it. Definitely a nice system.
How big is your dish? I've

I have an Andrew bifilar helical antenna for the240-320 MHzMILSAT
band, same antenna pictured in back of their old catalogs. I paid a
lot of money
What, exactly, is a helicoil antenna?

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
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
a crossed Yagi antenna at a Ham Swap for a price I
couldn't pass up. Still have the Quagi, just in case.

There is an amazing gentleman out in the Palm Desert area ... met him at the
Palm Springs HamFest earlier this year. He fabricates some beautiful 2M Yagis
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
