Other Considerations
The strength of each transmitted signal must be considered when planning your
antenna installation. Two parameters are usually listed to indicate transmitted signal
strength: output power of the radio transmitter, and gain of the antenna system.
With these points in mind, the design of antennas and components supplied with the
RoamAbout Outdoor Kit are based upon the following principles:
The following distances are required before contacting the Antenna Installation

Distance between the antennas:
Cable length needed at building A:

•
Output Power of radio equipment is often subject to maximum limits as
defined by local radio regulations. Consequently output power is not by
definition the way to enhance wireless performance.
•
High gain antennas are larger in size than low gain antennas, and are
characterized by a narrow focus of the radio beam. These two characteristics
make it more difficult to aim the antennas, and/or adjust antenna alignment to
optimize the performance of the wireless point-to-point link.
•
An output power and antenna gain that comply with the maximum limits as
defined by local governing bodies concerning radio transmissions.
•
Enhanced radio sensitivity for optimal reception of RoamAbout radio signals
transmitted by remote antennas.
