Should be fine.  That change in elevation will eliminate the air stratification 
multipath for the most part.

9402’ at one end and 7271’ at the other.  Mountainous with no trees almost no 
vegetation.

  Good point, what does the path look like?  If it is hill country or 
mountains, high to low etc diversity may not be needed.  But if the path is 
flat at essentially the same elevation, it may be needed.  If the path is flat, 
same elevation over smooth stuff or water diversity will most likely be needed.

  You need spatial diversity for a link that far, and a good air protocol so 
PTP400 with one 4ft or larger dish at one end and  two 4ft dishes (separated by 
50ft? Link planner would tell) at the other.

    I have a customer that needs a low speed very long link.

    Link is 64 miles, 2200’ elevation change.

    I’m looking at a Last Mile Gear connectorized PTP100. Reliability is 
definitely needed.

    Any other radios you guys would recommend?

    900MHz is out due to noise floor.
