Bob, You shouldn't need either if you plan on using a dual-band antenna. However, You'll get good uplink, but your downlink will likely suffer. Then's when you want to use a Diplexer to split your receive signal out so that you could put a preamp in line or even better, a beam antenna and preamp.
Jeff Moore -- KE7ACY ----- Original Message ----- From: "Bob- W7LRD" <w7...@comcast.net> I'm really trying to "absorb" all this diplexers / duplexor thread. Specifically I have a new FT-8800 and want to run FM sats from my truck. Not wanting to reinvent the wheel would a simple dual band whip suffice. Then maybe requiring a preamp, and how all that works maybe with a di / du etc. My head is starting to hurt. 73 Bob W7LRD _______________________________________________ Sent via AMSAT-BB@amsat.org.
