MAXI-CHOKER Coax Line Isolator, 1-61 MHz, 3KW, SO-239 In/Out, -30Db CMRR

MC-1-3000

MAXI-CHOKER Coax Line Isolator, 1-61 MHz, 3KW, SO-239 In/Out, -30Db CMRR MC-1-3000

MAXI-CHOKER Features:

- Uses proprietary Multi-Mix, Multi-Core, Multi-Turn(TM) ferrite technology for maximum choking (up to -35 dB common mode noise rejection) and maximum bandwidth

- 3 KW PEP, 50 ohm SO-239 connectors In/Out, 1-61 MHz

- Available with ground stud/static bleeder option for solving tough RFI issues

- Available with dual stud/wingnut output for ladder line interface

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

- 2-5 times more common mode noise rejection, wider bandwidth and higher power then competing filters


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, at 1/2 wavelength intervals along the coax feed line and also at the entrance to the radio station.

This choke is available with a SO-239 input/output and ground/static bleeder stud (optional) for attachment to a ground rod. Use an isolator every 1/2 wavelength for the antenna operating frequency (include velocity factor in calculation). Use the ground lug option for long coax antenna feed lines (over 1/2 wavelength at the operating frequency of any antenna system in the near field of the coax).
