Where did you get that antenna? did you make it or buy it? I keep thinking about making a pringles can one but never did. I would be really interested if it could pick up the tower from my spot on turn 1 that way I can access my slingbox to watch the tv coverage.
I think watching your home tv is going to be a real stretch for this type of setup. In order to be really effective you need to have a strong antenna on
both sides of the connection.
Pringles can or "cantenna" for the commercial version fine for getting wifi from the guy next-door or similar but that's about it. Good commercial rigs make claims of several miles under the right conditions.
