This is clearly the lazy way to do this, but it's also the least expensive. Here's the deal. My major network digital programming comes from 43 miles away in Philadelphia. My CM4248 and CM7775 handle those pretty well 90% of the time. I have three local channels, one of them being PBS. My roof-top antenna is aimed for optimum reception of the Philadelphia channels. However, the local channels broadcast about 20 degrees off from where the antenna is pointing, so while they're closer, I have trouble maintaining a lock.
The easy answer (depends on your definition of easy) is to buy a rotor so I can move the antenna.
An alternative solution that I'm toying with is combining the signal from the rooftop antenna with the powered set-top antenna I was using to successfully bring in the local channels before I put up the big guy.
So my question is, is it feasible to combine these two sources so that the set-top powered antenna (positioned for the local channels) will supplement the rooftop antenna and allow me to bring in all of these channels without a rotor?
If so, do I need a special combiner that would allow power to flow through both ports? (I tried a diplexer, but the TV (non-power pass) wouldn't let me combine these two)
Obviously I'm trying to avoid not only another $100 investment but also time on the ladder, which is a harrowing experience in my case anyway.
