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.

These impedance transformer kits have been designed for the Do-It-Yourself (DIY) enthusiast and Instructor workshops on baluns and ununs for antenna matching and RFI use.

The impedance transformers are classified in ratios of 2:1 (100:50 ohm) to 16:1 (800:50 ohm).  The outputs can be configured as balanced (Balun) or as unbalanced (unun) with respect to the inputs which are considered all unbalanced coax at 50 ohms.  All impedance transformers are designed for 1.8-31 MHz unless otherwise specified.
