The mast-mounted components of each pre-amp should both have weather protection, it is the wallwarts and power-inserter that you'll need to evaluate. Plus, I think only UHF side of your UVSJ passes power, hence the need to insert power for the VHF pre-amp upstream of the UVSJ.

I am amazed at how much the preamp has helped.
When done properly, a pre-amp makes moot all of the downstream losses, at the expense of a small hit to SNR at the beginning of the signal chain.
