Where should I attach the grounding wire when installing this antenna on a fiberglass mast? The top U-bolt clamping it to the mast looks like a convenient spot, as it offers a place that ground connector could slip under locking washer and it adjoins the base.
Would this be a sufficient ground, or do I need to insert a coaxial lightning arrestor? The antenna will be mounted a couple of feet over my roof in Denver, Colorado. As my transmitter will be getting only 26dBm (~400 mw ) to the antenna, I am tempted to avoid inserting additional loss into the feed, if safe.
