• Available with Ground Lug/Internal Static Bleeder Option - Excellent Replacement for Hygain BN4000D Balun Used on Beam Antennas

MAXI-CHOKER feed line chokes are used to suppress common mode current carried on the outside of the coax braid which is often responsible for receiver noise and RFI in the receiver/transmitter. These chokes are very useful for suppressing RFI common mode current at the antenna feed point or at a ladder line to coax junction, like a G5RV antenna.

Note: Color may be white or black depending on on inventory at time of order. Also available with SO-239 in/Out (MC-1-1500 or MC-1-3000) or with static bleeder/ground (MC-1-1500GB or MC-1-3000GB).
