yes it's better discussion

Greetings:
We live in a very rural area of Alaska and our current radiophone is very expensive and very unreliable. We have a clear unobstructed view to the cell tower in a village downstream from us and the distance is 20.93 miles the same distance our radiophone currently operates on. Could use some direction as to what part of the forum I should post my questions in such as is there any measuring equipment I could acquire to determine signal strength first? Then would like to hear what others in our circumstances may be using. Thank you for your consideration.
