A 70 cm preamp is always useful! There are a lot of them out there, but my
experience is that ARR and SSB Electronics make the best. Definitely not
the cheapest, though.
Be certain to get one which is RF switched, and which will handle your rig's
power. No matter how careful you are, you WILL transmit into it someday.
Been there, done that.
You will need to split your single antenna jack on the rig to two lines.
Almost any diplexer gives 50 db+ separation, but there are a few which are
only 30 db or so. Worth checking.

Subject: [amsat-bb] Receive Pre-Amps for 70cm
I recently purchased an M2 Satellite Eggbeater antenna kit with the
intention of working satellites from my shack. I think this antenna will
work best with a pre-amp for the 70cm band that perhaps I can put in my
attic close to the antennas. Who makes a good pre-amp for this situation to
mate with my FT-8800 radio. Thanks, Peter KC2RBX
