Be Aware of Seasonal Changes
When conducting the initial Site Survey, the fewest possible missed packets for a given link is better. However, seasonal changes may
affect the signal strength and the total signal quality. Radios installed outside with 50% missed packets in the winter months may have
80% or more missed packets in the summer when leaves and trees interfere with radio reception.
During spring and summer, leaves may
block more of the radio signal.
A good signal strength in winter doesn’t
always mean you’ll get the same signal
strength the rest of the year.

Basic Remote Antenna Installation
A remote antenna system is any antenna system where the antenna is not connected directly to the radio. These systems typically use
coaxial cable to connect the antenna to the radio. When installing a remote antenna system, always include a lightning arrestor or coaxial
surge suppressor in the system. Remote antenna systems installed without surge protection invalidate the warranty of the radio devices.
Surge suppressors should be properly grounded and mounted at ground level near where the cabling enters a building. Install the surge
suppressor indoors or inside a weatherproof enclosure to minimize corrosion or component deterioration. For best results, mount the
surge suppressor as close to the ground as possible to minimize the length of the ground connection and use a single-point ground
system to avoid creating ground loops.
For more detailed information about how antennas work and how to install them, refer to Antenna Basics, Banner document 132113 (also
included as a chapter within the product manual).
