1500 Watt PEP Rated 1:1 CUBE™ Balun for dipoles
* Help keep RF out of the shack.
* Provides maximum transfer of RF to the antenna.
* Suppress radiation from the feeder cable
* Makes the antenna radiation pattern predictable.
* Outperforms the competition by 24 dB common mode rejection! (see graphs)
* Reduces QRN and TVI to the neighbors.
The CB-1-1500 balun is useful as common mode feed line chokes or unbalanced coax to balanced antenna interface. SO-239 input to side terminal/eyebolt output. . Rated 1500 Watts PEP from 1-61 MHz. Common mode rejection up to -38dB over the frequency range. The CB-1-1500 is the balun version and the CU-1-1500 is the unun version (coax in and coax out).
Use as line isolator, antenna interface, or as a common mode choke to keep RF on the antenna and off the outside of the coax braid. Much more effective then our snap on ferrite beads as this balun which provides a higher choking impedance over a broad frequency range.
For most effective results, use another feed line choke (coax noise filter) at the radio. Helps reduce noise floor too by choking off common mode neighborhood noise picked up on outside of coax braid acting as secondary receive antenna
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.
THESE DEVICES ARE NOT FOR LIGHTNING PROTECTION AND PROVIDES NO PROTECTION FOR LIGHTNING STRIKES!!!!!
