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.

Need a 4:1 and 1:1 HYBRID balun? Check out our CB-4-1-1500/5000 with feedline choke built into same box as impedance transformer for ease of installation!

TUBE feed line chokes/Line Isolators are used to suppress common mode current carried on the outside of the coax braid which is often responsible for receiver noise and RFI in the receiver/transmitter. These chokes are very useful for suppressing RFI common mode current at the antenna feed point, at 1/4 wavelength intervals along the coax feed line and also at the entrance to the radio station. They are available with various input and output connectors so as to conveniently connect to standard output connectors already installed on your feed line.

Palomar Engineers TUBE feed line chokes are designed to have 2-5 times more choking impedance over a broader frequency range than competitor units in similar packaging. Each choke has the choking impedance and effective frequency range on the product label so you can choose the product best suited for your application.
