Frequency Range < 2:1 SWR (MHz): 1-31

PEP Power Rating (watts): 1500

Enclosure Size: 4" x4" x 2"

Antenna Compatability: Dipoles: Extended double zepp, folded 2 wire, off center fed (OCF); Loops: Horizontal, vertical - coax fed

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 (see swr graph)

Need a 4:1 and 1:1 HYBRID balun? Check out our CB-4-1-1500/5000 with feedline choke built into same box as impedance transformer for ease of installation!

TUBE feed line chokes/Line Isolators are used to suppress common mode current carried on the outside of the coax braid which is often responsible for receiver noise and RFI in the receiver/transmitter. These chokes are very useful for suppressing RFI common mode current at the antenna feed point, at 1/4 wavelength intervals along the coax feed line and also at the entrance to the radio station. They are available with various input and output connectors so as to conveniently connect to standard output connectors already installed on your feed line.

Palomar Engineers TUBE feed line chokes are designed to have 2-5 times more choking impedance over a broader frequency range than competitor units in similar packaging. Each choke has the choking impedance and effective frequency range on the product label so you can choose the product best suited for your application.
