This is an Excellent point. I use and antenna-mounted pre-amp with a bandpass filter. I have a Quadrafilar helix in my attic (I live in FL so do that for lightning and hurricane protection). I use a bias-T to power the preamp via the coax. This setup works very well even under my roof.

Did you try adding a preamp to your rx setup?

Hi all, I am in search of an antenna that I could use to receive the 2 meter telemetry signals from AO-73, Nayif-1, etc. While I am having good success with my Yagi setup, I would like to eliminate any computer control of the antennas. My question is what would be a suggested antenna I could possibly build? I'm testing out a Lindenblad in RHCP, but so far (2 days in the air) I'm not seeing any decodes.
That's pretty much my experience - using a non-directional antenna for satellite telemetry decoding was a dismal failure. In several years of listening, the number of packets decoded could be counted on the fingers of one hand. I used several different antennas with similar results (or lack thereof).
