Comet CBL-1000 - High Power 1.0 KiloWatt 1:1 Balun
The CBL 1000 is a newly designed high-power model, rated up to 1KiloWatt with an HF frequency range of 1.7-30 MHz. The output connector is the usual SO239 socket. Comet have re-designed this balun from the old CBL30 mode which it replaces, and it has a very strong, tough case and should be good for many years of operation!
1:1 Balun (The Choke)
The most common balun. It does not change the impedance; it simply ensures that the RF current on the two sides of a balanced antenna is equal and prevents "common mode" current from flowing back down the outside of your coax.
- Best for: Centre-fed Dipoles, Inverted-Vs, and Yagi antennas that naturally have an impedance near 50 Ohm.
- Function: Prevents the coax shield from becoming part of the antenna, which reduces RFI (interference) in your shack.
