Special pricing on extra inventory of CB-9-1-1500TSNN (N connector input, top stud output))

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-9-1-1500TSNN is housed in a 4” x 4” x 2” waterproof housing with N connector input and stainless steel eye bolts on the top. Also available is eyebolt output on sides and SO239 input as part# CB-9-1-1500B.

For BBTD and T2FD antennas, the termination resistor for the antenna is a Model # TR-500-600 or for higher power dissipation use two 1000 ohm resistors in parallel, (Part# TR-1000-600)
