[Motorola] Re: MTR-2000 Questions

[Glenn Little WB4UIV]

A good site manager will require an isolator. This keeps everyone good 
neighbors and helps reduce RF pollution.

However there are not many good site managers. They are after the rent money.

If all fixed RF emitters were required to have functioning isolators, the 
RF spectrum would be MUCH cleaner.
