80-10 Meter Loop antenna (288' wire) + 500/1500/5000 Watt PEP rated 4:1 Current Balun + internal 1:1 Current Balun in one enclosure + 6 insulators for support

* Complete package - just add coax

* works multiple bands with ease

* can be configured as delta, square, rectangle or multi-sided horizontal loop (6 insulators included)

* Choice of 500, 1.5K, or 5KW PEP rated baluns to suit power needs

* No need for extra feed line choke as it is built into the 4:1 balun enclosure

After many requests we have created a compact, special balun for OCF and loop (Skyloop or Delta loop) antennas. The CB-4-1500OCF is a CUBE enclosure containing a multi-core, broadband 4:1 impedance transformer in series with a 1:1 current balun for extra common mode current choking to keep RF current off the outside of the coax braid and on the antenna where it belongs. The extra choking action also means that the coax feed line will not act as a radiator causing unnecessary RF interference (RFI).

1500 watt is in 4" x 4" x 2" enclosure and 5KW is in 4" x 4" x 4" enclosure.

ADD MC-1-3000 Choke for radio end of coax to reduce common mode noise on coax up to 6 "S" units!

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.
