Model CB-5-1500TS- 5 to 1 Balanced Output Balun

(SO-239 in with output connectors on top similar to CB-2-2000 balun shown in picture)

Purpose. This balun is designed to match 250 ohms balanced to 50 ohms unbalanced up to 1500 watts PEP power from 1.8-61 MHz. It provides conversion from unbalanced 50 ohm coax to a balanced 250 ohm load/antenna feed point and gives a 5:1 impedance step-up to reduce VSWR on the coax feed line. The balun is housed in a 4” x 4” X “2 NEMA weather resistant box with SO-239 coaxial input and a ¼” stud terminals with wing nut on the top for output

This balun is DC grounded and will bleed off static electricity but it is NOT A LIGHTNING ARRESTOR.

Application. For use on Bruce Arrays and similar antennas with balanced 250 ohm feed point requirements.

Use a coax noise filter to reduce noise from any antenna or a line isolator to electrically isolate the coax braid from becoming part of the antenna.
