Product Details
MPN: OCFFLC

Off Center Fed (OCF) Antenna Feed Line Choke for 1/4" coax (1.8-61 MHz)

Got an off center fed antenna fed with RG-8X size coax and having feed line radiation (RFI) problems?

This feed line choke will help solve the problem of feed line radiation (which causes RFI to nearby object close to you coax) as well as Improving antenna pattern by preventing your dipole from becoming a tripole

Simple to install as an extension to your existing coax feed line using a female to female barrel connector (available separately).

Install quickly, reduce your coax radiation issues and start working more DX with a better transmission (and reception) antenna pattern.

Also works with single or multi-band loop antennas using a 2:1, 4:1 or 6:1 transformer without a choke.


TUBE feed line chokes/Line Isolators 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 1/4 wavelength intervals along the coax feed line and also at the entrance to the radio station.  They are available with various input and output connectors so as to conveniently connect to standard output connectors already installed on your feed line.

Palomar Engineers TUBE feed line chokes are designed to have 2-5 times more choking impedance over a broader frequency range than competitor units in similar packaging.  Each choke has the choking impedance and effective frequency range on the product label so you can choose the product best suited for your application.
