6:1 Baluns/Ununs

Model CB-6-1500 is a 6:1 (300:50) voltage balun housed in a Nema enclosure box (4″ x 4″ x 2″) with two top studs capable of input power levels up to 1.5KW PEP/500 watts continuous when used with a matched load. The 6:1 ratio takes 50 ohms input and matches to 300 ohms balanced output from 1.8-61 MHz with SWR < 1.5:1 under matched load conditions. A great balun for windoms, OCF antennas >60 feet over ground, Hertz and folded dipole antennas, T2FD etc. Dual core, Ruthroff style balun. Choose version with side eye bolts for wire attachments for OCF dipole use.

High Power rated at 1.5KW/3KW/5KW (option) PEP (FT8 mode at 1.5KW)

Broad frequency range of 3-30 MHz for < 2:1 SWR into matched load

Compact 4" x 4" x 2" (1.5KW) or 4" x 4" x 4" (3KW/5KW) light weight weatherproof enclosure

Quick, easy deployment with either halyard hoist and side eyebolts or to stud outputs (all 1/4" stainless hardware)

Choice of BALUN (balanced outputs) or UNUN (unbalanced output and ground)

Model CB-2.25-1500, 3000, 5000 is a 2.25:1 (112:50 ohm) multi-core balun used to translate a 50 ohm input to 112 ohms at RF power levels up to 5000 watts PEP when used with a matched load such as single band delta loop, quad or loop skywire. This assembled balun features a multi-core configuration for increased power handling and flatter frequency response to over 30 MHz. With a matched 112 ohm load the SWR over the frequency range is very consistent from 3-30 MHz and SWR is less than 2:1 over the range allowing easy tuning by most radio internal antenna tuners or an external tuner.
