Description
TinyFilter – 2 Meter
By K6STR and N6ARA
The 2m TinyFilter is a compact, lightweight bandpass filter that mounts directly to your radio and dramatically reduces interference from strong out-of-band signals like FM broadcast, TV, and public service transmitters. Ideal for SOTA operators and anyone working near busy RF sites, it passes the 144–148 MHz amateur band with low loss while providing high rejection of nearby out-of-band signals.
Kit – Requires soldering connectors, PCB enclosure board, and heatshrink. All small surface mount components on the filter board arrive pre-soldered and tuned.
Assembled – Arrives fully assembled and tuned.
