4.1.5 Antenna & Feedline Selection
NOTE: The transceiver is a Professional Installation radio system and
must be installed by trained professional installers, or factory
trained technicians.
This text that follows is designed to aid the professional
installer in the proper methods of maintaining compliance with
FCC Part 15 limits and the +36 dBm or 4 watts peak E.I.R.P
limit.
Antennas
The equipment can be used with a number of antennas. The exact style
used depends on the physical size and layout of a system. Contact your
factory representative for specific recommendations on antenna types
and hardware sources.
In general, an omnidirectional antenna (Figure 4-5) is used at the Access
Point station site. This provides equal coverage to all of the Remote
Gateway sites.
NOTE: Antenna polarization is important. If the wrong polarization is
used, a signal reduction of 20 dB or more will result. Most
systems using a gain-type omnidirectional antenna at the
Access Point station employ vertical polarization of the signal;
therefore, the remote antenna(s) must also be vertically polar-
ized (elements oriented perpendicular to the horizon).
When required, horizontally polarized omnidirectional
antennas are also available. Contact your factory representa-
tive for details.
