HCJB GLOBAL TB 1000

GENERAL DESCRIPTION

The TB1000 transmitter operates in the four shortwave tropical bands and the two lowest international shortwave bands (2.3 – 7.3 MHz).

It was developed to meet the need for a compact, easily transported shortwave broadcast station that can be set up and operated anywhere in the world.

By delivering program content up to a distance of 300 to 400 miles during daytime hours, it is the perfect tool for delivering the gospel to remote and sparsely populated regions.
