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.
80-10 Meter Loop Antenna System with 4:1 Balun and Choke Combo, 3-30 MHz, 500/1500/5000 PEP OptionProduct DetailsMPN: PAL-8010LOOP-500, -1500, -5000Country/Region of Manufacture: USAInput ohms/Output ohms: 50 in/200 outFrequency Range < 2:1 SWR (MHz): Balun rated at 1.8-61 MHz for 1.5KW, 1.8-31 MHz for 3KW/5KWPEP Power Rating (watts): 500W/1.5KW/5KWInput Connector: SO-239Output Connector(s): Eyebolts/Wing NutHardware Type: Stainless SteelEnclosure Size: 4"x4"x 2"(1.5KW), 4"x 4" x 4"(1.5KW/5KW)80-10 Meter Loop antenna (288' wire) + 500/1500/5000 Watt PEP rated 4:1 Current Balun + internal 1:1 Current Balun in one enclosure + 6 insulators for support
* Complete package - just add coax
* works multiple bands with ease
* can be configured as delta, square, rectangle or multi-sided horizontal loop (6 insulators included)
* Choice of 500, 1.5K, or 5KW PEP rated baluns to suit power needs
* No need for extra feed line choke as it is built into the 4:1 balun enclosure
After many requests we have created a compact, special balun for OCF and loop (Skyloop or Delta loop) antennas. The CB-4-1500OCF is a CUBE enclosure containing a multi-core, broadband 4:1 impedance transformer in series with a 1:1 current balun for extra common mode current choking to keep RF current off the outside of the coax braid and on the antenna where it belongs. The extra choking action also means that the coax feed line will not act as a radiator causing unnecessary RF interference (RFI).
1500 watt is in 4" x 4" x 2" enclosure and 5KW is in 4" x 4" x 4" enclosure.
ADD MC-1-3000 Choke for radio end of coax to reduce common mode noise on coax up to 6 "S" units!
