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
Generator RFI testimonial:
Bob Received your order in a timely fashion. Tried the generator kit on Sunday & it drops the noise from S9 to S5 and took out all the electrical noise. I may want some more toroids from you at some point for other interference problems I have here. Ken VE3KCY

Want to make up your own RFI kits for a particular operation? Here are links to some of typical RFI solutions used in portable operations:
If you use a computer for logging in your portable operations, RFI getting into computers will often lock up your computer and/or radio and a computer RFI suppression kits may be helpful
Make your expedition or portable operation a pleasant and fun outing and remember to take along your RFI kits so you have more time to operate rather then to troubleshoot intermittent or noisy receiver conditions.
Portable Antenna Kits
If you need an effective portable antenna which folds up for transport yet is easy to deploy at your operating site, consider the BULLET series of end fed wire antennas.
