No you can't unless the original equipment manufacturer designed an amp
as part of the original system and had their system certified with that
amp.

Unlicensed freqs don't require a license however you can not legally add
an amplifier to a system (in this case, your 5 GHz backhaul) that was
not originally certified with the amplifier that you want to use.
Hams, who are licensed and who share some frequencies with unlicensed
operators do not need an additional license to legally use an amplifier.
To avoid mis-use and illegal use of ham amplifiers by unlicensed
operators, legitimate sellers of ham amplifiers (and indeed, any
amplifier) normally request that you show proof that you are a ham in
order to purchase an amplifier.
Unfortunately for our industry:
1. 95% of the WISPs who use external amplifiers are doing so illegally.
2. 95% of the companies who sell external amplifiers to WISPs are
skating on thin ice.

I am planning to install a 5Ghz backhaul from my main tower to a
remote. It will have the antenna on the top, 150' of LMR-400 and the
radio at the bottom. To make up for the loss, I ordered a 500mw amp
from L-Com. Unfortunately, they cancelled the order saying I need a
HAM license to purchase it. I thought unlicensed freqs dont require a
license?
