Will lightning damage Whelens non-metallic speakers more than a conductive, metal speaker?
A. No. Whelen’s omni speakers are made of fiberglass reinforced Lexan® and Whelen’s directional speakers are fiberglass. In either case this is a non-conductive material. Lightning will seek the path of least resistance, which is the steel pole mounting bracket and its associated ground wire. The pole top mounting bracket is a nice lightning rod.
