Over 90% of commercial cellular, paging, broadcast, communications and
microwave installations all have elevated cable runs. I'm not sure what you
mean by your statement about the dangers.
ANY ungrounded cable represents a voltage potential difference to
ground. Their being elevated doesn't seem to me to make much difference to
potential lightning damage than any other installation method (underground,
etc.). What about the "cone of protection" offered by the tower itself?
That alone should prevent a direct lightning strike to the cables. If
lightning hits the tower, everything that is at a different voltage potential
can arc including cable to cable, tower to cable, etc.
I'm going to cc. the reflector as I don't know who put on the original

I sorta disagree with this sentiment. Don't bury the mike, but don't bury
the key either.
When I got my General back in 1979, I tried HF phone, but found I couldn't
communicate as well with my meager antennas as I could on CW. So I did a
bit of both. By the next year, I upgraded to Extra.
Biggest problem with most folks isn't that they operate phone, but they
fail to find out how much fun CW can be. So strive for some balance.
Oh, and don't forget to try some VHF FM, CW and SSB, as well as RTTY, SSTV,
Packet and other modes. It is a big hobby!
