Choice of BALUN (balanced outputs) or UNUN (unbalanced output and ground)

Model CB-2.25-1500, 3000, 5000 is a 2.25:1 (112:50 ohm) multi-core balun used to translate a 50 ohm input to 112 ohms at RF power levels up to 5000 watts PEP when used with a matched load such as single band delta loop, quad or loop skywire. This assembled balun features a multi-core configuration for increased power handling and flatter frequency response to over 30 MHz. With a matched 112 ohm load the SWR over the frequency range is very consistent from 3-30 MHz and SWR is less than 2:1 over the range allowing easy tuning by most radio internal antenna tuners or an external tuner.

16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
