I was surprised when I hooked this up and the signal strength was only about 67%. This is marginal for my roof mount Wingard Sat antenna and also for my home system, but King's tech support told me this is normal for this sat dish. I had perfect conditions to receive a signal yet this is all I could get. If I had less than perfect conditions I probably would not get a high enough signal to even see the Direct TV programming. Seems like a poor design to me.
