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!
Due to many requests for antenna static bleeders, we have developed a product line of static bleeders for coax and for ladder line applications. Static electricity is caused by many situations including high desert wind, atmospheric conditions, etc. You may hear static crashes or have a buildup of static electricity that my be annoying during a radio conversation and it may be harmful to solid state electronics if high voltages are present on the RF input to your equipment.
A static “Bleeder” which shorts the direct static voltage to ground while leaving the RF frequency voltage unaffected if very beneficial particularly to those operations in desert conditions where low humidity, high static buildup are quite common. The SB-1 and SB-2 coax static bleeders work on coax line and the SB-3 static bleeder is meant for ladder line.
THESE DEVICES ARE NOT FOR LIGHTNING PROTECTION AND PROVIDES NO PROTECTION FOR LIGHTNING STRIKES!!!!!
