2) Antenna type and proper installation and aiming if applicable – Unless the users are
generally in close proximity to the unit – use of a high gain antenna is desirable. High
gain antennas include a 5 dBi omni-directional antenna and a 10 dBi yagi directional
antenna. For the broadcast radio, if the area to be covered is in a single direction from the
unit, it may be desirable to use a directional antenna to concentrate the antenna gain in
the direction of the user(s).
For the embedded Cellular modem, it may not be adequate to use the included duck
antenna. A higher gain 7 dBi omni-directional antenna as well as a 12 dBi directional
panel antenna is available.
3) Coaxial cable length and type – Keep antenna cables as short as possible. Avoid using
adapters. Use coax that has lower loss for high frequencies – such as Times Microwave
LMR240. Avoid using RG-58 cable.
4) Rover antenna type and condition – confirm that the rover users are using the correct
antenna. Any additional height that can be added to the rover antenna is useful – such as
a backpack with a short pole and adapter for the duck antenna.
