1500/3000 Watt 6:1 CUBE Balun™ – Model CB-6-1500/3000
Model CB-6-1500/3000 is a 6:1 (300:50) balun housed in a NEMA enclosure box (1.5KW in 4″ x 4″ x 2″, 3KW in 6" x 6" x 4") with two top studs capable of input power levels up to 1.5KW PEP watts when used with a matched load. The 6:1 ratio takes 50 ohms input and matches to 300 ohms balanced output from 1-61 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. 8 core, Use “EB” version with side eye bolts for wire attachments for OCF dipole use.
Typical SWR and impedance transformation from 1-61 MHZ shown below:
This transformer requires a feed line choke to isolate the coax feed line from the antenna. A coax noise filter is also recommended.
Due to many requests for antenna static bleeders, we have developed a product line of static bleeders for coax and for ladder line applications. Static electricity is caused by many situations including high desert wind, atmospheric conditions, etc. You may hear static crashes or have a buildup of static electricity that my be annoying during a radio conversation and it may be harmful to solid state electronics if high voltages are present on the RF input to your equipment.
A static “Bleeder” which shorts the direct static voltage to ground while leaving the RF frequency voltage unaffected if very beneficial particularly to those operations in desert conditions where low humidity, high static buildup are quite common. The SB-1 and SB-2 coax static bleeders work on coax line and the SB-3 static bleeder is meant for ladder line.
