MFJ Wall Mount 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 feedpoint 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 connector. 4" W x 2 ⅛" H x 2 ¾" D
