High Power rated at 2KW/5KW (option) PEP (FT8 mode at 1.5KW for 5KW PEP model)
Broad frequency range of 1.8-61 MHz for < 2:1 SWR into matched load. 5KW model is 1.8-31 MHz
Compact 4" x 4" x 2" (2KW) or 4" x 4" x 2" (5KW) light weight weatherproof enclosure
Quick, easy deployment with either halyard hoist or side mounting tabs
Choice of BALUN (balanced outputs) or UNUN (unbalanced output and ground)
Model CB-2-2000 is a 2:1 (100:50) quad core balun used to translate a 50 ohm input to 100 ohms at RF power levels up to 2000 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 60 MHz. With a matched 100 ohm load the SWR over the frequency range is very consistent from 1.8-61 MHz and SWR is less than 2:1 over the range allowing easy tuning by most radio internal antenna tuners or an external tuner.
Note: CU-2-2000SO picture shown CU-1.5-1500SO product but input/output connectors are correct.
50 ohm coax to 75 ohm balanced output baluns are useful for low (< 1 wavelength) dipoles exhibiting 75 ohm characteristic impedance or for matching to balanced ladder line whose endpoint impedance is near 75 ohms.
50 ohm coax to 75 ohm CATV coax connections are easily done with a 1.5:1 unun with SO-239 connectors on input and output. Likewise 50 ohm coax to unbalanced verticals or loads near 75 ohms can be matched with a 1.5:1 unun.
