Installing the SiteNet 450 Network 3
3.5.1 Antenna Considerations
Note – Please use care when removing the radio antenna. The
SiteNet 450 antenna contact tip is designed for maximum efficiency
and very low loss. To maintain its integrity, do not remove the top cap
from the radio housing.
Make sure that you mount the base and repeater radios as high as
possible. An increase in the antenna height increases your line of sight
and is the most effective way to increase the radio’s range. Consult
your license for the legal limits on antenna height.
Line-of-Sight Obstruction
Objects placed near the antennas, especially metal objects, can
severely limit antenna efficiency. If an antenna is to be mounted on a
mast, make sure it is mounted so that its radiating element is
completely above the top of any obstructing source, if possible.
Figure 3.12 shows the optional infrastructure antenna mounting for
the SiteNet 450.
