I bought a pair of in-line Trimble amplifiers but I can't find any specs.
Anyone know the gain?
They are in a machined stainless steel box with two "N" connectors.
Trimble sells them bundled with a long antenna cable so that the amp (I
assume) compensates for the cable loss. I opened one up. I'm very sure
they are preamps intented for being in the antenna feed line.
I won these on ebay for $0.01 for the pair, $5.00 for shipping. The seller
paid more than $5.01 for postage and lost money on the transaction. I
bought them because even if they were dead the cases are usfull. Now I
think I want to run one of them ahead of a passive splitter and have
multiple receivers on one antenna
Would be good to know the gain but I have no way to measure RF above about
80MHz.
