Just an update on my feed status. I have the antenna up and have been running into many snags. First was a cable short in the connector, which I had the guy come back and resolder it. Now the antenna receives great, but unfortunately the sensitivity on my scanner is extremely poor due to intermod from FM broadcast, at least I think, and probably other sources that I still don't know.
I have been looking into some filter options, but they are all so expensive, and I have no clue what is my primary source of interference. On the other hand, if I don't use a filter, I basically wasted 500 bucks on the antenna install

These I am told are excellent filters:
http://www.parelectronics.com/scanner.phpI know there is a filter which basically blocks out everything but the civil airband, but I don't want to miss out on milair comms and everything else I listen too, which includes a very broad spectrum.
Just wondering if any of you in the Liveatc community have experienced similar problems and what steps you have taken to resolve them.
