AMPEGON ANTENNA SYSTEMS HP-RCA

GENERAL DESCRIPTION

ROTATABLE CURTAIN ANTENNA (TCA)

photo Ampegon Antenna Systems HP-RCA

The rotatable curtain antenna system is the most flexible solution available today. Covering a 360° angle at the touch of a button, the TCA offers best investment efficiency.

The folded half-wave and rigid (steel) dipoles are an integral part of the steel construction. Tubular shafts are used as base sections and house all equipment needed to operate the antenna, such as drive system, feeding system including coaxial rotary joint, matching unit, broadband balun and antenna selector switch.

Thus all parts that are susceptible to climatic and/or environmental exposures, including the exposure to electromagnetic fields, are well protected.

Lattice shaft sections are used on top of the tubular sections, for the cross arms, supports of dipoles and reflector screens. All steel parts are of highest quality design to ensure an optimal weight of the overall system.

Accessibility is key to the design of the Ampegon rotatable curtain antennas, making inspection and maintenance work quick and easy.

TECHNICAL HIGHLIGHTS

The TCA has all the highlights of the rigid dipole antenna and in addition offers the following benefits for highest flexibility.

Access to all specified frequency bands of the allocated shortwave broadcasting range (Standard Design, without tropical bands)
Electric control logic to operate the entire network and to assure that the antenna is tuned in the direction of the respective coverage area over the shortest possible path
Smooth, jointless starting and breaking to a standstill
High rotation speed of 1 degree per second
High positioning accuracy of < 1 degree
Monitoring and remote control of all operational functions

The height (h) is according specific performance requirements. The stated range is assuming single-hop transmission and can be seen as a rough guideline for design purposes. In any case the range is dependent on specific ionospheric propagation conditions.
