Hybrids (NN:1+1:1)

Balun Hybrids include an impedance balun (2:1, 4:1, 6:1, 9:1, 16:1, etc) and a 1:1 balun (choke) in a single enclosure. Use on OCF, loop, terminated dipoles and similar coax fed antennas requiring an impedance transformer Suppresses common mode current on the coax outer braid (prevents your dipole from acting as a tripole!).

After many requests we have created a compact, special hybrid balun for Terminated Folded Dipoles (TTFD) and Broad band Terminated Dipole/loop (BBTD) antennas. The CB-9-1-1500 is a CUBE(TM) enclosure containing a multi-core, broadband 9:1 impedance transformer (50 ohm coax input to balanced 450 ohm output) in series with a 1:1 current balun for extra common mode current choking to keep RF current off the outside of the coax braid and on the antenna where it belongs. The extra choking action also means that the coax feed line will not act as a radiator causing unnecessary RF interference (RFI). Rated for full 1500 watts PEP and 450 watts CW (ICAS). 1.8Mhz – 61 MHz.

CB-9-1-1500EB is housed in a 4” x 4” x 2” waterproof housing with SO-239 input and stainless steel eye bolts on the side for ease of connection to your wire antenna. Top eye bolt acts as an antenna hoist. Also available with top studs for post or wall mounting (Model # CB-9-1-1500TS)

Termination resistor for the antenna is a Model # TR-500-600
