On the ground, in houses, and other places where people reside, the exposure levels from radio base stations are normally below 1 percent of the limits. Only in the close vicinity of the
This paper proposes an antenna solution for direct air-to-ground (ATG) communications, particularly focusing on the challenges and potential of the digital airspace vision.
An antenna network provides increased coverage, redundancy, and reliability for satellite communication. It enables continuous data transmission and
To simplify, the following charts show how many miles you can usually communicate over normal terrain in suburban or rural areas with different
To simplify, the following charts show how many miles you can usually communicate over normal terrain in suburban or rural areas with different types of radios, power levels, and station
The ground station antenna should be at least 15 feet above the ground—20 feet is better and 30 feet even better. If roof mounted, the antenna should be mounted near the highest point on the
