I am in the process of building a Ramsey rcvr preamp kit that covers 
from below 160 meters to around 1 ghz. It will be used with my 160 meter 
rcv loop. Since it is broadband I want to build a preselector front end 
for it consisting of a parallel LC circuit. I may even put another LC 
circuit at the o/p of the preamp as well.

What is the Q that I should use for the parallel LC circuits? I have 
been digging and have found other circuits but nothing that gives me the 
Q. The L and C combos are infinite. I assume a high Q but how high? 200? 
100?

The input and output of the preamp will be grounded on xmit.

Help.
