Sira

VHF ANTENNAS

SIRA's VHF line includes:

• Band I panel antennas for horizontally polarized broadcasting, suitable for directional or omnidirectional configurations on triangular or square towers. High gain and feed-point protection via fibreglass radomes.

• Band III panel antennas for horizontally or vertically polarized broadcasting, suitable for directional or omnidirectional configurations on triangular or square towers. Antenna feed lines are protected by fibreglass radomes. Yagi, reduced bandwidth antennas (DAB and DAB+) and broad band Log Periodics complete the range of SIRA antennas for band III.

All VHF SIRA dipoles are made of stainless steel to guarantee longer-than-average durability, even in harsh climate conditions (such as high levels of pollution, air salinity or acid rain). All dipole antennas are able to be pressurized, which is a characteristic of the most complex antenna systems and it is often necessary to guarantee reliability.
