Andrew offers a full line of optional components for terrestrial microwave antenna systems.
Antennas include one or two side struts,
depending on model. Where one side strut is supplied, it includes
a stainless steel threaded rod fine azimuth adjustment. Where two side struts
are supplied, one is adjustable (has fine azimuth adjustment) and the other
is fixed (adjustable but without fine azimuth adjustment).
Antenna mount structural members are hot-dip galvanized steel or aluminum.
Fixed hardware is hot-dip galvanized steel. Adjusting hardware, including
adjusting rods, is stainless steel. Some mounts use a swivel clamp for azimuth
adjustment. Most mounts have threaded fine elevation adjustment.
Radomes are available for most Andrew antennas. Radomes reduce wind
loading to the tower while providing added protection for the feed from the
elements. There are two types of radomes, flexible and molded. Flexible radomes
are provided on shielded antennas and molded radomes are options to standard
and focal plane antennas. All radomes have a standard minimum wind survival
of 125 mph (200 km/h).
- High Wind Environment Options
High wind options that exceed the standard 125 mph (200 km/h) wind
survival rating are available in 155 mph (250 km/h) and 200 mph (320 km/h)
survival rating. These heavy-duty antenna versions feature strong back structures
for maintaining alignment accuracy in adverse and severe wind conditions.
Use the "W" prefix for 155 mph (250 km/h), and the "S" prefix for
200 mph (320 km/h) survival ratings.
- Corrosive Environment Options
The corrosive environment option is available for most antennas. This
option provides long term protection in marine or salt and most industrial
environments including chemical and fossil fuel areas. A special epoxy paint
applied at the factory provides added protection. In addition, corrosion
inhibiting compounds and protective sealants are applied during installation.
Note: High wind and corrosive environment prefix codes are optional.
