Product Details

After many requests we have created a compact, special balun for Terminated Folded Dipoles (TTFD), Broad band Terminated Dipole/loop (BBTD) and V beam antennas with termination resistors at each end. The CB-16-1-1500 is a CUBE(TM) enclosure containing a multi-core, broadband 16:1 impedance transformer (50 ohm coax input to balanced 800 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 – 31 MHz.

CB-16-1-1500EB 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-16-1-1500TS)

Termination resistor for the antenna is model # TR-1000-375 for single resistor termination.

OCF antennas are very convenient as they will allow multiple bands of operation with a simple wire antenna which is fed off center with a 4:1 OCF Current balun with built in feed line choke,
