I bet most of the guys and gals here will recommend to consider each antenna and preamp pair as a single unit in this particular case! …

That is, the preamps are as close to the antennas as practical, and your arrester/polyphasors mounted near the grounding connection through a nice tin-coated copper braid and connects the RF to your feedline to the shack. Except that you must make sure your arrester does not block any DC needed by your preamps. In which case you may need to power the preamps *not* through the cables.

I'm installing a pair of M2 circularly polarized yagis. I have a long coax run, so I'm going to use SSB Electronics preamps mounted on the 8' tower.

I have a ground rod by the base of the tower with a couple of lightning arrestors that the two coax runs go through, but I was curious what to do about protecting the inputs to the preamps? Do I use a second pair of lightning arrestors between the antennas and the preamps? Or just mount the preamps on the shack-side of the existing lightning arrestors?
