MAXI-CHOKER Coax Line Isolator/Balun, 1-61 MHz, 3KW, SO-239 In/Stud Output, G5RV/ZS6BKW Replacement

MC-1-3000LL

MAXI-CHOKER Coax Line Isolator/Balun, 1-61 MHz, 3KW, SO-239 In/Stud Output, G5RV/ZS6BKW Replacement MC-1-3000LL

MAXI-CHOKER Features:

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

- 3 KW PEP, 50 ohm SO-239 connectors In dual screw terminal output for ladder line, 1-61 MHz

- Hi choking resistance 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 and off center fed antennas.

- 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 with high common mode choking to isolate the coax braid from becoming part of the antenna.

- Available with ground lug/internal static bleeder option


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. Ladder Line shown NOT included.

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.
