MINI-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 has a SO-239 input and 1/4" top studs output.
For Higher Power needs use our MAXI-CHOKER 3KW version part# MC-1-3000LL
If you need a unbalanced output (SO239 output) instead of a balanced stud output, see MC-1-500SO with SO239 output and input..
