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.

Product Details
MPN: CB-1-1500TS
Input ohms/Output ohms: 50 ohms in, 50 - 150 ouhms output
Frequency Range < 2:1 SWR (MHz): 1.8-61 MHz
PEP Power Rating (watts): 1500
Enclosure Size: 4 x 4 x 4
Antenna Compatability: G5RV/ZS6BKW/Dipole

The CB-1-1500DS Antenna Antenna Tuner Balun is a 50 ohm to 50 ohm, multi-core feed line choke designed to provide high choking impedance between a balanced ladder line feed line antennas (zepp, G5RV, extended double zepp, etc.) or single ended antennas like 1/4 wave verticals and a remote antenna tuner (including an automatic antenna tuner with only a single output and ground, like SGC-230, Icom AH-4, etc) short 50 ohm coax feed line (to antenna tuner) at a power of 1500 watts PEP from 1.8 to 61 MHz.

The input and output connectors are double studs marked +/-.

The CB-1-1500DS is configured as a Guanilla transmission line transformer with balanced outputs (current balun configuration). It is best used when ladder line impedance seen at the end of the ladder line to balun connection is close to 50-150 ohms. Enclosure box is 4″ x 4″ x 2″. Typical choking impedance range is 1K-10K ohms from 1-61 MHz.
