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.

.
SPECIAL ORDER SABRE 2:1 CUBE Balun™ – (1.8-30 MHz)
(Original product part # was 770013S - circa 1999)
Model SABRE-2-2000 is a 2:1 (100:50) quad core balun used to translate a 50 ohm input to 100 ohms at RF power levels up to 2000 watts PEP when used with a matched load. This assembled balun features a quad core configuration for increased power handling and flatter frequency response to 31 MHz. With a matched 100 ohm load the SWR over the frequency range 1.8 to 30 MHz is shown in the following table measured with an AIM 4170 network analyzer. Notice that the conversion from 100 to 50 ohms is very consistent from 1.8-31 Mhz and SWR is less than 1.5:1 over the range allowing easy tuning by most radio internal antenna tuners or an external tuner. Graph is for a 2:1 balun often used with delta loop, log periodic, horizontal loop antennas and HF Radar.
Input connector is 50 ohm type N (SO-239 also available - inquire).SABRE-2-2000 is in a NEMA 4x4x2 weatherproof box with mounting flanges at bottom to attach to fixed location (mast, wall, beam antenna, etc.).
Eye bolts and studs are all stainless steel for long life.
