Installation
Antennas
It is important that any antennas are installed in a suitable
location with an adequate ground plane. Ideally, multiple
antennas should be separated by a minimum of a
wavelength (at the lowest frequency), whilst still retaining
a good ground plane for each antenna. Therefore, for a
400MHz system, the ideal separation should be a minimum
of 0.75m (~30in), and for 150MHz system the minimum
should be 2.5m (~98in).
Warning: If installing an antenna near people it is necessary
to ensure the minimum separation is maintained. This
particularly important where prolonged exposure is likely.
