I have put up a 15-foot searchlight pole with a ladder (both made of aluminum) and was wondering how to ground them if lighting was to strike them. It will house a single GRS Searchlight head with a mechanism inside. If anyone has any documents or has signals of their own I would love to hear what you did. If you need more information let me know.
Thank you in advance,

How is it mounted to the ground? If there are bolts in a concrete base it may already be grounded. Another option is to go to the big box hardware store and get a grounding rod (a 6 or 8 foot copper rod). Pound it into the ground and tie a grounding strap or a wire (8 AWG should do) to the signal base or mast. Does it have a pointy finial at the top? I think those are there to dissipate static charge and not just decoration but I could be wrong on that. I have one if you need it.

A 108 page paper on the FRA website on lightning and railroad signals. I haven’t read it yet, but if I find anything interesting I’ll let you know.

I poured a concrete pad and put four 1 inch bolts into that. The signal is bolted down with two nuts to each bolt. It has a flat aluminum cap similar to this one.

Thank you for your help and sorry it to me so long to respond.

In 1975, when I was living in Sacramento, I went on a road trip with my parents and younger sister, who were living in Santa Rosa at the time, to visit relatives in Colorado and Iowa. I noticed that every farm house in Iowa had lightning rods. I later saw why as one evening I witnessed a spectacular thunderstorm move in at sunset. You seldom see that up here in the Puget Sound Region of the PNW.
