Broad frequency range of 1.8-61 MHz for

Compact 4" x 4" x 2" (2KW) or 4" x 4" x 4" (4KW) light weight weatherproof enclosure

Quick, easy deployment with either halyard hoist or side mounting tabs

Choice of BALUN (balanced outputs) or UNUN (unbalanced output and ground)

Model CB-2-2000 is a 2:1 (100:50) quad core balun used to translate a 50 ohm input to 100 ohms at RF power levels up to 2000 watts PEP when used with a matched load such as a delta loop, quad or loop skywire. This assembled balun features a quad core configuration for increased power handling and flatter frequency response to over 60 MHz. With a matched 100 ohm load the SWR over the frequency range is very consistent from 1.8-61 MHz and SWR is less than 2:1 over the range allowing easy tuning by most radio internal antenna tuners or an external tuner.

OCF antennas are very convenient as they will allow multiple bands of operation with a simple wire antenna which is fed off center with a 4:1 OCF Current balun with built in feed line choke,
