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.
50:112 (2.25:1) CUBE™ Balun 3-30 MHz, 1.5KW/3KW/5KWProduct DetailsCountry/Region of Manufacture: USAType: BALUNInput ohms/Output ohms: 50Frequency Range < 2:1 SWR (MHz): 3-30PEP Power Rating (watts): 1500/3000/5000Enclosure Size: 4" x 4" x 2" (1.5KW), 4" x 4" x 4" (3KW/5KW)Weight (pounds): 3Antenna Compatability: loops, quads, 112 ohm input antennasHigh 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.
