AMSTERDAM—
Ampegon, a supplier of shortwave, mediumwave, and longwave equipment, has
unveiled two new concepts for antenna design: a shortwave folded diplole antenna
system and a mediumwave folded monopole antenna system.
The shortwave folded diploe antenna
system is available in the RF power range up to 50kW for domestic shortwave
transmission. Designed with Ampegon components and optimized to lower power
specifications, the 50 kW system offers simplification without loss of
performance. The system also features key performance indicators like VSWR ≤ 1.5
in the operational frequency range band and a gain of 8 dBi. The design consists
of tubular structures for the suspension of the dipole and is designed for wind
speeds up to 99 mph.
The mediumwave folded monopole is
also a 50 kW antenna system and is fully grounded with no need for a base
insulator for the placement of the antenna. The antenna consists of the mast and
radiating element; the guy ropes supporting the mast are each divided by a
single insulator. A minimum number of insulators are installed, making
maintenance simpler. The newest type of insulator used in the antenna system
features silicon protection and shows a ruggedness toward environmental
influences.
For more information, Ampegon will
be located at booth 8.D35 during IBC 2015.
