Yes, i think you are right. For your application UHF CB does seem to be the
best way to go. Unfortunately for me in my application every degree will
count :(

As an aside - the new AOCP(S) and AOCP(A) licences allow hams to use the
13cm (2.4GHz) band with output power far in excess of unlicenced ISM
equipment (although you have to remember that encryption CANNOT be used for
amateur radio comms, which rules this out as an option for /actual/ use of
WiFi). This could allow you to use a "test" signal on 13cm which is a lot
closer to the real thing compared to UHF CB. The differences in wavelength
could affect propagation wrt obstructions. Just a thought...
