Is it brand loyalty or just dealer loyalty/non loyalty. I have found it interesting looking at some licenses in the metro and every few years when a change is made to some systems (I am referring to business systems ) such as add a new repeater add more channels, they seem to be with s new dealer- radios are first purchased from dealer A, upgrade to the system adding a new repeater is with dealer b, switching to Digital is with Dealer C. I am a bit at how often some businesses jump from dealer to dealer, just adding to the systems not always full replacements.
