[Help!] Very Odd Signal Problem

Hello,
Few weeks ago I installed a satellite mast in my backyard. It is about 3 metres tall. I have a 36" motorized dish. My dish is aimed correctly, I land perfectly on every satellite along the horizon. (82, 91, 110, 118.8, 119, 129). I am having trouble receiving signal from some tp's, maybe about 3 or 4 from each satellite. I have absolutely no signal and quality from them. This is where it gets even more weird, I will be watching a channel and everything works great for about 30 min. Then the picture starts getting blocky/choppy. I change to a different channel and the same thing happens, it works great for about 30 min then gets choppy again. I am thinking it could be a grounding issue. I have my system grounded in the house through a grounding power bar. I am thinking I need to ground the dish and mast with a copper rod.

Any thoughts?
