6.6 Antenna & Feedline Selection
NOTE:
The transceiver is a Professional Installation radio system and
must be installed by trained professional installers, or factory
trained technicians.
The text that follows is designed to aid the professional
installer in the proper methods of maintaining compliance with
FCC limits. Part 15 limits the power to +36 dBm or 4 watts
peak E.I.R.P limit. For WiMAX DTS radios, the maximum
allowed ERP is 1 Watt per MHz.
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, a sector type antenna is used at the Base Station site. This
provides equal coverage to all of the Subscriber sites.
At Remote Gateway sites and units in point-to-point LANs, a directional
Yagi (
Figure 36
) antenna is generally recommended to minimize
interference to and from other users. Antennas are available from a
number of manufacturers.
