Do you advertise this, though? Seriously, I think a lot of installers (at least in my area) are missing a great opportunity. I would have gladly paid the installer to put up an outdoor antenna and properly run the cabling to support local OTA for my 622. But, I couldn't find anyone who seemed to offer that service. I wound up doing it myself, and not doing nearly as good a job as a decent installer could have done. Our yellow pages is chock-full of ads for satellite installers, yet not a single one mentioned traditional antenna installation. I'm sure some do it, but how is the typical consumer to know?
In my area, neither satellite provider offers HD locals, and I wouldn't expect them to for quite some time. In addition, the transition to digital TV is less than a year away. In my mind, that equals a pretty big market for antenna installation. Offering that service would benefit a lot of people, advertising such would give an installer a nice advantage over the competition, too, not to mention a nice revenue stream that they control.
Just a thought...
