MFJ MFJ-2912

Wall-Mounted Isolation Balun

Mounts on the exterior wall of your shack to keep RF out of your operating position and

away from internal house wiring. Also prevents electrical noise generated in your location

from migrating up to the antenna feed point and raising your receiver’s noise floor.

Toroid-style transmission-line choke is rated for maximum legal power on SSB/CW.

Delivers an impressive 30+ dB of through-transmission (S21) common-mode isolation on 80-10 meters. Convenient disconnect point for lightning protection. All stainless hardware and rugged components. SO-239 connectors. 4” W x 2-1/8” H x 2-3/4” D.
