[amsat-bb] SSB SP-7000 rejection

Hello all,

I'm planning a new antenna system and planning on using an SSB preamp on the 430 downlink side. The 7000 uses helical bandfiltering. My antenna separation will be on an 8' fiberglas boom. Will desense be an issues? Should I plan on using a bandpass filter such as a duplexer?

Thanks and 73 de Tim, K4SHF
