RFI/EMI Solutions from KHz to GHz
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
* 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
