MAXI-CHOKER Features:

- Uses proprietary Multi-Mix(TM) technology for maximum choking (up to 5K ohm) and maximum bandwidth

- 1.5 KW or 3 KW PEP Option, 50 ohm SO-239 connectors In dual screw terminal output for ladder line or dipole driven element, etc. effective 1-61 MHz

- Up to -48dB common mode suppression solves tough RFI issues

- Works for all coax fed antennas from 1.8-61 MHz (160-6 meters) - excellent for multi-band beams, verticals, dipoles, off center fed antennas, tri-band beams.

- 2-5 times more choking resistance, wider bandwidth and higher power then competing filters

- great replacement choke for G5RV/ZS6BKW antennas or as a 1:1 ladder line to coax interface for Flagpole OCF type antennas with high common mode choking to isolate the coax braid from becoming part of the antenna.

- 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).

Mobile RFI kits work two ways: They suppress RFI from on board computers and other sensing/control devices in your vehicle that may cause your radio to be a VICTIM of RFI, and second they suppress RFI generated by your radio as a SOURCE which may affect your on board computers or other devices.  Mobile operations of HF radios (1-30 Mhz) tend to experience more RFI effects than VHF/UHF mobile stations.  If you have both HF and VHF installations in your vehicles, you may need both kits.

To address separate solutions we have developed two separate RFI kits: one for HF (1.8-300 MHz) mobile installations and another for VHF/UHF (30-1000 MHz) mobile installations.  Each kit uses the appropriate ferrite mix for the frequency range desired.
