6:1 Baluns/Ununs

Model CB-6-1500 is a 6:1 (300:50) voltage balun housed in a Nema enclosure box (4″ x 4″ x 2″) with two top studs capable of input power levels up to 1.5KW PEP/500 watts continuous when used with a matched load. The 6:1 ratio takes 50 ohms input and matches to 300 ohms balanced output from 1.8-61 MHz with SWR < 1.5:1 under matched load conditions. A great balun for windoms, OCF antennas >60 feet over ground, Hertz and folded dipole antennas, T2FD etc. Dual core, Ruthroff style balun. Choose version with side eye bolts for wire attachments for OCF dipole use.

Product Details
MPN: BA-4-1000DC
Type: balun or unun
Input ohms/Output ohms: 50 in, 200 out
Frequency Range < 2:1 SWR (MHz): 1-55
PEP Power Rating (watts): 1500 Watts PEP
Antenna Compatability: Balun: Ladder line to coax interface

Purpose. Model BA-4-1500DC is a 4:1 dual core balun kit (assembly required from parts supplied) used to translate a 50 ohm input up to 200 ohms at RF power levels up to 1000 watts when used with a matched load. It provides conversion from unbalanced coax to balanced ladder line/antenna feed point and gives a 4:1 impedance step-up to reduce SWR on the coax. Place at the junction of the balanced line and the coax to convert from balanced line to unbalanced coax.

KIT Contents. The kit consists of a 2 ferrite toroidal cores, two colors of insulated wire, a SO-239 UHF connector with stainless steel hardware, and an instruction manual.

Assembly time: About 1 hour, illustrated manual included with purchase.

Radio Club idea:

Buy 10 for a club do it yourself construction project - you can learn something and also build an end fed antenna (just add wire).

Product picture shows assembled item of all components in kit.

NOTE: for higher power and a true current balanced 4:1, use our BA-4-1500DC dual core 4;1 balun kit
