Model CB-9-1500 is a 9:1 multi-core, balanced output balun housed in a water resistant enclosure with top stud/wingnuts (TS) or Eye bolts (halyard top hoist, side eye bolts/outputs) used to translate a 50 ohm input up to 450 ohms at RF power levels up to 1500 watts PEP when used with a matched load. With matched 450 ohm load the SWR over the frequency range 1.8 to 61 MHz is less than 2:1 on the coax feed side. Actual SWR is under 1.25:1 from 1.8-180 MHz so very useful for 30-150 MHz also - see graphs for specific details

Features

* Wide Frequency Range 1.8-161 MHz, usable to 180 MHz < 1.25:1 into resistive load

* High Power, 1500 watts PEP (up to 61 MHz)

* Convenient side tab mounting feet

16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
