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.
