when using wifi or cell freqs the lower the dbm the better....70 is better than 88..
is it the same with the on screen signal meter... I am running 47 and the pic is good.
What is the minimum low and high..???

The meter on the Dish receivers you can't really go by. You use to be able to because they went on a 1-125 scale. Then Dish "neutered" the meter so I think mid 50's to low 60's is good

Also Eastern Arc and Western Arc have different meter scales...what system do you have?
Can you post transponder signals here?

500 single set up with 625 box. in MT/Idaho.. how do you post transp signal??

Actually with wifi the higher the dBm the better. -70dBm is better than -80dBm because -70dBm is a higher number.

Anyway, with a 500, pointed at 110/119, you want at least 60-65 on TP 16 on both sats.
