Hello group,
I received my broadband VHF/UHF/WX Satellite RX Preamp and installed it direct to the feedpoint of my 70 cm antenna. Put 11 volts DC on it, however no increase of noise on the receiver. And I do not notice any amplication of received signals.
Taking the preamp out of circuit results in same signalstrength as before without preamp.
Any ideas?
