1500 Watt PEP rated 4:1 Current Balun + internal 1:1 Current Balun in one enclosure
After many requests Palomar Engineers has created a compact, special balun for OCF and loop (Skyloop or Delta loop) antennas. The CB-4-5000OCFEB 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). Rated for full (5KW PEP) and has a frequency range of 1.8-31 MHz and does not cover 6 meters.
CB-4-5000OCFEB is housed in a 6” x 6” x 4” waterproof housing with SO-239 input and stainless steel eye bolts on the side for ease of connection to your wire antenna. Top eye bolt acts as an antenna hoist. Use this balun combination when you DO NOT have a vertical radiator.
** Note the 5KW models are made to order and shipment time is approximately 7-10 days after order date.
We recommend a 21%/79% offset for best all band results. If you use 66%/34% offset, do not use on 15 meters as the impedance mismatch may damage the balun under high power operations
