Does anyone know where to find information on who sells the best quality lowest noise LNB's for a Dish Network system? Up north here (around 60 degrees N. Latitude) I'm using a 4' dish with a JVC 301 receiver. The maximum signal strength reading from the Dish Network on screen meter is 73. That's on the strongest channels on a good day. Unfortunately it doesn't take much weather to knock the signal out. Wish there was a Consumer Reports type test done on LNB's.
