Hello Jim, Do you still use the GulfAlpha 'Easy Sat' antenna? I'm looking for any advice on improving performance. I have already installed the diplexer as shown in the article below but it seems I'm getting no good signal on the 70cm uplink.

Yes, I lose some signal on terrestrial use, but ti helped cut the coupling, and desense, down quite a bit. 73, Jim KQ6EA On 01/19/2014 06:56 PM, Gabriel - EA6VQ wrote: > Hi all, > > I have a coupling problem in my station when trying to work FO-29.
