Model CB-2-8-1500 is a 2:1 and a 8:1 balanced output (balun) housed in a Nema enclosure box (4″ x 4″ x 2″) with a top eyebolt halyard hoist, two side studs for 2:1 and two additional side studs for 8:1 outputs, each capable of input power levels up to 1.5 KW PEP when used with a matched load. The 2:1 ratio takes 50 ohms input and matches to 100 ohms output and the 8:1 ratio takes 50 ohm input and matches to 400 ohms output between 1-31 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 2:1 and the the 8:1 in a single package! – just buy the CB-2-8-1500 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 2:1 and 1 of the 8:1 terminals on opposite sides, then the output wlll be 312 ohms or about a 6:1 balun!
