I'm still an amatuer with 60 foot tower and 4 element beam located in a secluded valley.

Your set up sounds professional. You have more steel in the air than my zoning laws would allow.

No wonder you got hit.  You have my sympathy and envy. wrote:

I assume you don't live in the lightning capitol of North America, central FL. I understand very well about lightning and static build up as do others who have posted here. I have three 199.99 footers as well as several other smaller ones. Unless you live in an area of little t-storm activity you have been very lucky. Having a lightning hit your tower is not if, but when.

I have spoken to several EEs who work at the local surge protection mfg company and since I have followed their advice I have had no damage even though the towers have been hit over the summer.

Nope, never been hit by lightning in over 30 years of hamming. Evidently you have had that misfortune.

Ever wonder if there might be something you don't understand about static build-up?

My tower is grounded by virtue of the tower leg bottoms stuck in sand and dirt below the concrete. I don't need any additional grounding.

The tower acts like a big lightning rod. Contrary to popular belief, lightning rods don't attract lightning, they dissipate static charge. At least mine seems to work that way. Your milage may differ. wrote:

You ever take a lightning hit? I have several times and it was uh....exciting. Towers were extensively grounded but not to a common
ground with the
house. Three tower legs are not an extensive ground and will not dissapate a direct hit and will likely make a beeline to your shack on
the coax to
finish the job on its way to your home grounding system through the
You are living on borrowed time with that attitude. Extensive grounding is your best friend and the insurance company's.

I fail to see why a ground is needed at all. Surely the lower two feet of tower is firmly embedded in dirt with the concrete anchor above that. If it was done that way those three tower legs should serve as some pretty good ground rods. At least my version of common sense tells

me so. I will have to admit that common sense has not always been kind. Sometimes it does not make sense at all and becomes just common bs. I am wondering what it might be on this topic? Anyone venture a guess?
