Hello to the group,
I have for sale a NEW, never used FF Systems FF-800 4-port controller
w/autopatch
(PCB Rev.E). The autopatch and IC-901 option are independent and
DO NOT use one of the ports to function like similar controllers, so
you still have all 4 ports available.
Would prefer to trade

They work okay. It's a nice one piece design so it is mountain top

My advice would be to use something without a gamma match. The A449-6 is a poor

I have mounted all four elements ON the tower leg, with no antenna mast. The

So you can mount it as close as you want. I would suggest that you add a

the bottom to keep the mast
I bought the exact EPROMs that I needed for my Tait from Digikey. Not too

If you want to use the 27C256, you will need to modify the EPROM socket
wiring. Manuals for the series I (EPROM version) are not available in

their web site. If you find the series I manuals in PDF, many folks

I use the MC2 connectors with the stinger. I trim the stinger back to about
1/2in. Then I affix an N barrel connector to the stinger with a pl259

I think you pretty much answered your own question.
Like so many other fiberglass antennas, I suspect something has broken
within. It might be repairable, but I'm not familiar with that antenna. And
I'm not a fiberglass antenna fan, this being one of the reasons.

Ralph,
Not much information to go on... What frequency? What model antenna? What
make and model duplexer? What type and length of feedline? What was the
return loss with the dummy load in place? How did you measure the desense?
Between what extremes did it vary? What troubleshooting steps
I had to cut mine to length for 146.34, did yours come with the cutting chart?
Also the set screws might of rattled out in the wind.

Folks,
Thanks for the antenna input. I think there are probably a few more
anti-fiberglass folks out there than anti-folded-dipole folks. My main
problem has been lack of an affordable folded dipole array with more
than 4 elements that covers the amateur 70cm band -- I like the

Tram antennas are. well, let's just say you got what you paid for. I
don't think I've ever seen a similar antenna that was lower in cost.

On VHF they of course are a little lacking, and I
