Compact 4" x 4" x 2" light weight weatherproof enclosure (6" x 6" x 4" box for 4KW model)

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.

2:1 (100:50) Baluns are useful between 50 ohm coax and 100 ohm balanced lines for loops, cubical quads, log periodics and other antennas where the impedance at the end of the feedline is 100 ohms (1/2 wavelength feedline).
