Questions. Would the tall trees be a problem? They have a lot of leaves. Also, what would be a good not to expensive stand alone over the air HD receiver for my older CRT HD TV? And could I use the same cables with a D* swm system? My roof would not be in the way so how high would the antenna have to be from the ground?
I'm starting to want to have the option of over the air HD for all our locals.
I don't think tall trees pose much of a problem, unless you are trying to use too small of antenna in relation to your distance from the transmitter. Some people report good results from mounting their TV antenna inside their attic, provided there is enough room up there, and they don't have a metal roof.
I'm not sure about the standalone HD TV tuner. I know they are available, but probably not a lot of demand for them. The tuners that were sold under the government's coupon program would receive the HD channels, but would only output in SD resolution.
Some of the newer DirecTV receivers allow free local OTA channel reception from an antenna, which will probably get you some additional channels (subchannels), on top of what is included for local channels as part of your satellite subscription. An additional module may have to be purchased for some of those receivers to allow you to do that, if it is not a built-in feature.
I'm not really familiar with how the SWM system works. The splitters I described in a previous post requires one outside for you to connect your satellite dish and TV antenna to, and one inside behind the TV to split it back out, sharing a single cable that is now just carrying your satellite signal to your TV, instead of running an additional cable through the wall.
I have a rooftop antenna on a single-story house with a low-pitch roof. No 2-story houses immediately around me, but the antenna is pointing directly at a cedar elm tree in my yard, and at a 2-story house about 300' away.
