Radio Works B1-5K-PLUS

Applications: Dipoles, trap dipoles, Inverted-V, Slopers, etc. Any application requiring a 50 ohm balun.

The B1-5K has a much higher isolation factor. If you need 6 meter operation, then this is the best choice. We built this balun as part of an antenna project for the Peace Corps in Zaire, Africa. They needed an antenna for a high power, high duty cycle application. Several commercial antenna systems had failed in similar service, so they asked us to build a bullet-proof system. We developed the B1-5K as the heart of that project.

I do not know of another balun with this combination of precision, specifications, high power rating, and construction quality. its design makes it remarkably saturation resistant. This prevents signal distortion and potential RFI problems that plague common 'Voltage-type' baluns.

Even with power overload and load mismatch, they survive. Applications: Dipoles, trap dipoles, Inverted-V, Slopers, etc. Any application requiring a 50 ohm balun. It has a much higher isolation factor. If you need 6 meter operation, then this is the best choice. B1-5K Plus is the answers to requests for a precision 160 meter balun.

The B1-5K Plus ia a Current-type baluns that can take abuse in stride. Even with power overload and load mismatch, it survives. It provide better output balance and far better reactance characteristics than 'Voltage-baluns' that require a nearly perfect load.
