A combination of surge protection and proper grounding is the key. We utilize a multi-point ground tester and find a large portion of our sites have poor grounds (less then 5 Ohms to earth) or some crack head stole the buss bars and copper. (Very likely in FLA). Testing has become part of our semi-annual maintenance. We also utilize static dissipaters to reduce the conditions for lightning to form around the site as well as surge protectors.
As far as Transtectors, The large one for the canopy is very well designed and works well. We have replaced all of the ALPU-ORT (PTP Transtector versions) with the new Motorola units. They stand up better, are made for hanging on towers and don't fill with water after baking in the sun for a few years.

We have had great luck with the transtector ALPU-POE for Canopy and have had great luck with the units that are recommended by redline for AN80. We're actually trying on a couple of sites a POE with Surge from Hyperlinktech.
