The VBI-360 is an electronic display that connects to your RS232 serial port or existing rotor control box to show your antenna's directive pattern on a Great Circle map. As you rotate your beam its coverage is clearly indicated by a selectable group of LEDs around the map periphery.

“Outstanding Product and Customer Service. I recently took delivery of the new I2C Beam Heading Indicator, which now provides an interface for rotors using RS232 protocol. Tom's support and help goes above and beyond what a normal manufacturer provides. The I2C program and settings can be changed at any time using a simple terminal program on a PC. And visitors always comment on it. Highly recommended! - Ed K6CTA
The VBI Plus is a joint ham venture between Tom, W3FRG and Robert, DK7NT.
