Posted on June 01, It is important to note that antenna gain is different than amplifier gain.
Additional Product Info
Antennas do not have a power source that allows the antenna to create additional energy to boost the signal. An antenna is similar to a reflective lens in principle - it takes the energy available from the source and focuses it over a wider or narrower area.

Antenna gain is then a measure of the amount of focus that an antenna can apply to the incoming signal relative to one of two reference dispersion patterns. Digi specifies all antenna gains in dBi. Thus an antenna with 2.
A reference dipole antenna is defined to have 2. So converting between dBi and dBd is as simple as adding or subtracting 2. Specifying antenna gain in dBd means that the antenna in question has the ability to focus the energy x dB more than a dipole.
Because higher gain antennas achieve the extra power by focusing in on a smaller area it is important to remember that the greater the gain, the smaller the area covered as measured in degrees of beam width think of an adjustable beam flashlight. In many cases a high gain antenna is a detriment to the system performance because the system needs to have reception over a large area.
