Ampegon to Install Shortwave Array Antenna

Will install its first rotatable shortwave high-power array antenna in North America

Ampegon says it is about to deliver and install its first rotatable shortwave high-power array antenna on the North American continent.

The system, which will be installed WBCQ in the United States, is designed for the transmission of shortwave signals of up to 500 kW, the high-power antenna offers different radiation patterns, an antenna gain of up to 23 dB and uses a technology characterized by a single-shaft structural design.

The tubular shaft with a diameter of four meters acts as a rotatable and supporting axis that is able to absorb static and dynamic forces originating from antenna components. This, explains Ampegon, allows the system to function under extreme weather conditions.

The antenna is made up of a low-band and a high-band array antenna, positioned back to back, each equipped with a reflector screen. Thus, WBCQ can access all shortwave frequency bands between 6 MHz and 26 MHz.

In addition, Ampegon points out that the computer-controlled and monitored system offers unlimited rotation capacity and will turn toward the coverage area using the shortest possible path. Intelligent drive control ensures the large rotating part of the structure is jolt-free, starting and braking to standstill with a high rotation speed of 1.2 degrees per second and a positioning accuracy of <1degree.

The system also features DC grounding, a minimal number of insulators and no insulation in structural parts.
