Outdoor Antenna Installation Guide 3-3
Other Considerations 3
In most literature concerning wireless outdoor products, two
parameters are usually listed to indicate transmitted signal
strength:
output power
of the radio, and
gain
of the antenna
system.
• Output Power of radio equipment is often subject to maximum
limits as defined by local radio regulations. Consequently
Output Power is not by definition the way to enhance wireless
performance.
• High gain antennas are larger in size than low gain antennas,
and are characterized by a narrow focus of the radio beam.
These two characteristics make it more difficult to aim the
antennas, and/or adjust antenna alignment to optimize the
performance of the wireless point-to-point link.
With these points in mind, the design of antennas and components
supplied with the RoamAbout Outdoor Kit are based upon the
following principles:
• An output power and antenna gain that comply with the
maximum limits as defined by local governing bodies
concerning radio transmissions.
• Enhanced radio sensitivity for optimal reception of RoamAbout
radio signals transmitted by remote antennas.

Appendix D - Calculating Range & Clearance
for detailed
information to help you calculate the optimal range of your antenna
system.
