I did both SAT TV and OTA TV for a while and had same problem with SAT TV. I would rather park in the shade then to watch the SAT TV it seems. The OTA CLEAR HDTV using my BATWING UHF Antenna then got used for the digital TV signals from the local towns. This was always better HDTV then what I got from the standard SAT TV anyway haha...
I eventually just stopped bringing along the SAT TV stuff from the house...
We downstream from the Internet if we want to watch some of those SAT TV cable channels.
Never wanted to pay the high cost for the automated SAT TV reception.
