Low-loss input bandpass filter for the 2m band...
Low-loss input bandpass filter for the 2m band from 144 to 146MHz with PGA-103+ very low noise preamplifier, +25dB gain.
The unit contains a high-selectivity, high-Q, low-loss -0.13dB bandpass filter with VLNA.
A 2m cm bandpass filter is integrated to suppress out-of-band signals from 70cm or 23cm stations.
Achieves better results than with two separate components, approximately 0.05-0.1dB lower NF, thanks to two fewer connectors.
Power consumption: +10-15V / 100mA
Supplied with a box for outdoor mounting.

These excellent results are the result of careful selection of components and meticulous design.
Thanks to input filtering, the combination of preamplifier and bandpass filter is much better protected against interference from strong out-of-band signals.
