MFJ-2911 - Boom-Mounted Yagi Balun

MFJ-2911 - Boom-Mounted Yagi Balun

This 1:1 current-choke style balun mounts on the boom of your HF or 6-Meter Yagi to transition from unbalanced feedline (coax) to the balanced driven element. It prevents unwanted pattern distortion from feedpoint imbalance, radiation from outer surface of coax shield, element de-tuning, RFI to consumer electronics and noise transfer to the radio's receiver.

MFJ uses a toroid style transmission line choke that is rated for maximum legal power on SSB/CW and that delivers an impressive 35 dB of through-transmission (S21) common-mode isolation.

Molded case, SO-239 connector.

5 " W x 2" H x 3" D
