From using my Dish Network VIP722 I gather the minimum signal is 65, and I usually get a 67-70. I am using a Jenson branded antenna I picked up eight years ago at big lots for $5. To my knowledge it does not have a signal amplifier as there is no place to plug it into an electrical socket. Right now I am getting a solid 82 signal an am 8 miles from my tower according to Antenna Web. My question would be is there anything I can buy that would increase the signal ?
