I have a 105 superdish that was installed a while back it was about a month before DP44's came out. My problem is very poor signal strength on the 105 satellite. I am getting in the 30's to 40's and it is making me lose signal when I watch local channels. Last time I checked it I was getting in the 60's but that was months ago. The DP34 I have is in my basement so I doubt that could be the problem. I did a check switch and the polarity for the 105 came back as even could that have to do with anything? I have no clue what the problem might be so any suggestion might help. If more information is required ask and i will get back soon as I can.
