Two tests must be performed on the antenna to ensure that it meets the requirements. For both tests, the antenna must be
integrated in its final form. That is, the antenna must be mounted on a representative housing that includes all metal objects
forming the ground plane or counterpoise.
Antenna testing requires an experienced operator and an anechoic chamber, a GTEM cell, or approved open field site. Your
Motorola OEM support representative can provide advice on this type of testing.
