Bill ... I would consider running the guy to the end of the house, and
attaching it SAFELY to the eave somehow ... You would be saving yourself from
the song "O great ... it's leaking AGAIN around the guy point" being sung ...

Rohn used to offer some hardware for eaves es such ...

And start planning NOW on how to PROTECT the tower/shack/house from lightning !
