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.
