The lower powered version of our popular CB-1-5000, the CB-1-1500AT Antenna Tuner Balun is a 50 ohm to 50 ohm, double core feed line choke designed to provide high choking impedance between a balanced ladder line feed line (zepp, G5RV, extended double zepp, etc.) and short 50 ohm coax feed line (to antenna tuner) at a power of 1500 watts PEP from 1.8 to 61 MHz. The CB-1-1500AT 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.
