Either your transverter must be dumb, or you use lossy cable.
Otherwise I see no reason for such preamps.
So I would first improve that situation before using cascaded preamps.
Any preamp causes additional noise and weakens your IP3

Hi All
I would like to know what is best in two stage preamp on 1296 , at the
moment I am using a cavity preamp as 1st stage and right after it a normal
(dj9bv)preamp with a total gain of round 35 db both at the feed.
Is it best to install the second preamp at a distant position from the 1 st
stage ? the reason I am asking as It seems that i have some overload on the
transverter on local strong signals.
thanks for the advice
