Antennas and QUATRA RED
Donor Antennas
The donor antenna is a crucial element when designing a public safety DAS. Typically this component is
mounted on the roof of the building and is exposed to signal interference caused by reflections or direct
signals hitting the antenna from every direction. To avoid excessive interference going into the repeater
is vital to pick an antenna according to the RF environment.
In low dense populated areas or rural areas, a wide-angle panel antenna may be an okay option since
the RF noise in those areas it's generally below the average. The Cel-Fi Wideband Directional Antenna
(A32-V32-101) it's a perfect option in these scenarios.
On the other hand, a high-isolation donor antenna as the Cel-Fi LPDA Antenna (A62-V44-100) is highly
recommended in urban areas with an RF polluted environment that will cause more noise.
