I have 3 filters for sale. All are in like-new condition. They have
only been used inside my non-smoking shack.
Use the bandpass filters whenever critical single band performance is
required, and/or when nearby radio stations are causing interference.
Excellent for multiple operator stations, and portable or permanent
use. Uses a twin section dual resonator scheme. All are 50 ohms,
non-polarized in rugged and water resistant aluminum enclosures.
