Transceiver Location
Placement of your FreeWave unit is likely to have a significant impact on its
performance. In general the rule of thumb with FreeWave is that the higher the
placement of the antenna the better the communication link - height is everything!
In practice you should also place the transceiver away from computers,
telephones, answering machines, and other similar equipment. The included 6
foot RS232 cable will usually provide ample room for placement away from other
equipment. To improve the data link, FreeWave Technologies offers directional
and omnidirectional antennas with cable lengths ranging from 3 to 200 feet.
When using an external antenna, placement of that antenna is critical to a solid
data link. Other antennas in close proximity are a potential source of interference;
use the Radio Statistics to help identify potential problems. It is also possible that
slight adjustments in antenna placement (as little as 2 feet) will solve noise
problems. In extreme cases, such as when the transceiver is located close to
Pager or Cellular Telephone transmission towers, FreeWave offers band pass
filters (a standard filter and a cavity filter) to reduce the out of band noise.
The FGR115W is waterproof and may also be mounted outdoors without
additional weather protection. The waterproof enclosure also requires an external
antenna, and includes a 6 foot data and power pigtail cable.
