[amsat-bb] Noise on 2 Meter Attic Antenna

[Les Rayburn]

I live in a very crowded, suburban neighborhood with a strict HOA. No outside antennas allowed. 

Luckily, I have a large attic with plenty of height. This has allowed me to mount a Az-El rotor with a 4 element 2 Meter Yagi, and an 11 Element 432 Yagi. Also found room a 15 element loop Yagi for 1.2 GHz. 

Everything works great except when I’m operating birds with a 2 Meter downlink. Noise in some directions can be very high on that band. I’ve eliminated all noise sources inside my own home, but have neighbors that are putting out a lot of noise across the VHF spectrum. 

This basically limits me to passes above about 20 degrees for those birds. Once I get up to a high enough elevation angle, the noise goes away. 

Anything else I can try? Would a 2 Meter band filter help?
