Opening a itelite or dbs antenna?

I assume the ITELITE DBS is an active and not a passive device as it has a circuit board? Where does it get additional power to boost the signal if the only connections are the original antenna connections?

We have to have conservation of energy.
Don't worry. No physical laws are being violated.

Antenna gain is achieved by beam shaping or directivity. Much like the difference between a typical light bulb which radiates nearly omnidirectional and a flashlight which collects and in some cases focuses the light in a particular direction.

This is why alignment must be maintained between controller and aircraft to achieve greater range.

In the parlance of RF design this omnidirectional aspect is referred to as isotropic. Antenna gain is expressed in dBi where the "i" is isotropic or 'as compared to'.
