The CB-4-1500 balun is a multi-core current balun with an enclosure box. Input is via SO-239 coax connector and output can be top studs (for ladder line) or side eye hooks (2) and top eye hook used as a halyard hoist for supporting your wire antenna. Rated 1500 Watts PEP Watts from 1.8-61 MHz (see SWR graph).
This transformer requires a feed line choke to isolate the coax feed line from the antenna. A coax noise filter at the radio end of the coax is also recommended to reduce coax cable common mode noise.is also recommended.
Useful on these type of antennas:
Dipole, double extended
Dipole, linear load, ladder line fed
Dipole, long, non-resonant
Dipole, off-center fed (OCF)
Dipole, snake type, ladder line fed
Long wire with ground system
Multi-band, remote balun
Useful out to 200 MHZ under 2:1 SWR
