We have one tower, where it's just a small site (a Rohn 25 with a couple of omnis on it), so initially I didn't bother with any sort of surge suppression, except for a cheap rate ubnt surge suppers going to the the property owner/customer's house (which is about 10 feet from the tower) - we'd lose the ethernet port on his router pretty much everytime a thunderstorm would go through, and more often than not a radio or two on the tower. I eventually got sick of dealing with it and put a GigE-APC on every ethernet cable (only at the base of the tower... nothing at the top), and it's been running for about a year now without a single problem. So yes, those things work and work well.
