Chapter 2: Installing the system
Radar distance
The minimum acceptable separation (d min.) between a radar and the
antenna is determined by the radar wavelength/frequency and the power
emitted by the radar. The tables below show some "rule of thumb" minimum
separation distances as a function of radar power at X and S band. If the d
min. separation listed below is applied, antenna damage is normally avoided.
"d min." is defined as the shortest distance between the radar antenna (in any
position) and the surface of the TracPhone antenna.
