the Keysight/Agilent FieldFox is also a wonderful piece of gear, 
comparable to the Anritsu.  I've used both, and it's nice to be standing 
on a roof (either in blazing sun, or pouring rain) with a self contained 
instrument that has a fair amount of capability.

I've not hung one off a tower, but I know someone that has dropped a 
Fieldfox from some height, and it survived ok. I think the Anritsu would 
be the same.
