Bangladesh Betar Goes With Ampegon
KABIRPUR, Bangladesh — Bangladesh Betar is the
state-owned radio broadcasting organization of Bangladesh. To optimize the
international shortwave coverage, it was decided to upgrade the existing
Kabirpur transmitting site with the new, flexible Ampegon HP-RCA 2/2.
Ampegon HP-RCA2/2 at Kabirpur, Bangladesh
Featuring easy integration with practically any
shortwave broadcast station, this was a good choice for the extension. The new
rotatable antenna was tested and handed over from Ampegon to Betar in September.
on a rigid dipole array and a tubular shaft, the HP-RCA 2/2 is a back-to-back
arrangement of a low-band and a high-band curtain antenna equipped with
2/2 dipole array configuration gives a good radiation characteristic and the
antenna gain of up to 19 dBi assures sufficient signal field strength in the
coverage area. The antenna operates to any azimuth and can rotate 180 degrees
in less than three minutes.
take into consideration the environmental conditions at the site, the antenna
is designed for a maximum survival wind speed of 150 mph and a maximum
operational wind speed of 75 mph.
using rigid λ/2 folded dipoles, which are mounted to the steel structure at their
“zero potential” point, the need of insulators in structural parts is
eliminated and perfect static grounding is assured. This and easy accessibility
are the reasons we feel that the HP-RCA 2/2 is one of the most reliable high-power
shortwave broadcasting antennas available.
antenna’s enhanced power splitting and dipole feed system is optimized for
outstanding bandwidth performance. This is even more important for Digital
Radio Mondiale operation, for which the new transmission system at Kabirpur is
proven design of the Ampegon rotatable shortwave antenna system is enabling
broadcasters to make major savings, thanks to the high overall efficiency and
the outstanding flexibility.
Ampegon is a new name to many. It was formed out of
Thomson Broadcast’s radio business along with several other technology
