Setup and Deployment Guide
Low gain “rubber duck” antennas that are mounted directly to Mesh transceivers are designed
for transmitting and receiving vertically polarized radiation. Hence, care must be taken to insure
close-to-vertical orientation of these antennas to avoid substantial signal loss due to polarization
mismatch. Additionally, attenuation sustained by use of these antennas inside vehicles can be
as high as 10 dB. Typically, losses are in the 4 to 7 dB range if the antenna is above the “metal
can” of the vehicle so that radiation and reception occur at window level.
