Output band pass filterEach preamplifier has a band-pass filter at its output to further help the front end of your radio not intermodular.
Preamplifier with integrated VOX circuit, coaxile relays and bias tee on board. It can work up to 100W and performs TX to RX switching automatically.
Ultra Low Noise INNOVATIVE Preamplifier available for the 2 meter band. Low noise figure (type 0.35dB with coaxial relay active).
Thanks to the notch filter present at the input it is possible to attenuate the broadcasting from 88 to 108MHz ..
It can be powered, as well as by the passing capacitor, also through BIAS TEE with a voltage of 9 to 15V and a maximum absorption current of 130mA .
