My first install. A 76cm dish with motor on a chimney mount TV pole. As the one Sat AV signature block says: "this is only temporary, unless it works!" I had a hard time trying to get my true south but managed to do so after 3 hours. Having two settings for the motor and dish was strange to me as was the whole concept the first time. (You mean I can point this at something that is miles up in the sky?). I could make the TV pole plumb but the chimney mounts for the pole were a bit shakey. That said, after 3 hours I got my TS sat! Not really on the arc though. Took many more attempts to get the arc and then could go from 157W to 85W before being blocked by a tree. It worked for 3 years before the chimney mounts became so loose from bending under the stress of the motor and dish it would be blown off the arc repeatedly. Now I'm using an undersized rafter mount! It's only temporary! Thanks for a fun contest!
