The MFJ-2911 is a 1:1 current-choke style balun that mounts on the boom of an HF or 6 meter Yagi to transition from unbalanced coaxial feed line to a balanced driven element. It is designed to prevent unwanted pattern distortion from feed point imbalance, radiation from outer surface of coax shield, element detuning, RFI to consumer electronics and noise transfer to the radio’s receiver. MFJ uses a toroid style transmission line choke rated for maximum legal power on SSB/CW. The MFJ-2911 is mounted in a molded case with SO-239 connector. The MFJ-2912 is similar but mounts on the exterior wall of your shack to keep RF out of your operating position and away from internal house wiring. The MFJ-2975 is designed for use with dipole antennas and transforms 75 loads down to 50 . Price: $39.95 each. To order, or for your nearest dealer, call 800-647-1800 or see www.mfjenterprises.com.
