Mario and Tom raise interesting points.

When I changed out the old TH6 for a nice shiny C31XR I worried about the 
insulated elements. I asked Force 12 about it. I was told there has been 
only one reported instance of insulator failure in that application and 
that was using "excessive" power levels.

Since it was inconvenient to do other wise, I simply put the thing up and 
forged ahead. After two seasons of running it (with max legal power) on top 
of the 71 foot shunt feed tower, the insulators are still functioning as 
insulators.

My coax is NOT taped to the tower leg, and is NOT grounded at the base 
either. This may be a lightning issue, but it would appear to not be a RF 
issue in this particular installation.

On the other hand, maybe it's better to be safe than sorry. Certainly 
everyone is not as lazy as I am!

73,

Larry - W7IUV
