Multi Ratio 4:1/6:1/9:1 CUBE™ Balun, 1.8-61 MHz, 1.5 KWProduct DetailsMPN: CB-4-9-1500Country/Region of Manufacture: USAType: Balanced output (BALUN)Input ohms/Output ohms: 50:200, 50:450Frequency Range < 2:1 SWR (MHz): 1.8-61 MHzPEP Power Rating (watts): 1500
1500 Watt 4:1/6:1/9:1 CUBE™ Balun – Model CB-4-9-1500
Model CB-4-9-1500 is a 4:1 and a 9:1 balanced output (balun) housed in a Nema enclosure box (4″ x 4″ x 2″) with a top eyebolt halyard hoist, two side studs for 4:1 and two additional side studs for 9:1 outputs, each capable of input power levels up to 1.5 KW PEP when used with a matched load. The 4:1 ratio takes 50 ohms input and matches to 200 ohms output and the 9:1 ratio takes 50 ohm input and matches to 450 ohms output between 1-61 MHz under 2:1 SWR under matched load conditions.
Now you don’t need to buy two separate baluns or guess which balun to use - you get the 4:1 and the the 9:1 in a single package! – just buy the CB-4-9-1500 and pick the output ratio that best matches your antenna tuner! (Note: you can only use 1 set of outputs at a time)
Application note: If you use 1 of the 4:1 and 1 of the 9:1 terminals on opposite sides, then the output wlll be 300 ohms or a 6:1 balun!
