Product Details

MPN: CB-4-5000EB

Input ohms/Output ohms: 50 in, 200 out

Frequency Range < 2:1 SWR (MHz): 1-31

PEP Power Rating (watts): 5000

5000 Watt PEP Rated 4:1 CUBE Baluns™

Th CB-4-5000 balun feature dual core ferrites configured as a current balun with a weather resistant enclosure box. Input is via SO-239 coax connector and output can be top studs or side eye hooks (2) and top eye hook used as a halyard hoist for supporting your wire antenna. Rated 5000 Watts PEP Watts from 1.8-31 MHz. Enclosure is 4″ x 4″ x 4″. Multi-core technology is excellent for high duty cycle modes like RTTY, Digital, AM, etc at 5KW PEP.

It is recommended that a feed line choke to isolate the coax feed line from the antenna. A coax noise filter is also recommended.

The high power ferrite impedance transformer series (> 1:1), configured with outputs to act as a baluns (unbalanced coax in to balanced load output) or as ununs (unbalanced coax input to unbalanced load output) are designed for demanding radio transmitter stations that run over 1,000 watts PEP or run continuous modes like AM, digital, RTTY, FM, etc. at high power levels. Radio contest operators, commercial shortwave broadcast, and industrial and commercial stations use these transformers for for a variety of balanced and unbalanced antenna loads. Baluns are typically used for balanced loads and antennas like dipoles, loops, log periodics, and direct feed yagi/beams. Ununs are used with verticals, end fed wires, horizontal dipoles, G5RV/ZS6BKW, Zepps, vertical wire beams, etc). All products are in an enclosed NEMA water resistant box with SO-239 input connector and stainless steel side/top studs with wing nuts or side and top eyebolts. The enclosure box has mounting “side feet” for attachment to a post or antenna boom using nylon ties.
