3. Still a problem, the unit is pulled and put on a bench and connect to a service monitor. Power, deivation receiver sensitiity et is checked.

The most common problem is always connecotrs, cable run and antennas

Interesting, how do you VSWR meter a UHF ariel? As I understand it, VSWR measures strength in gain wave length gain to to particular radio set and ariel on attached to a particur location and also can be altered according to the plane set with the ariel?

Now isn't UHF a point to point signal, not a wave signal?

So therefore a Db gain reading wouldbe needed.

And further more, with VSWR tuning a AM set you tune the SWR by trimming the correct ariel to get that elusive 1.1.. But how do you tune the uhf Ariel?
