There fore it is up to the OP to find out if the pole is in a place that is the landlords property, (as I posted earlier) and that it is ok for them to use it, thn if the installer decides to do it, thats up to him.
Would I do it that way, NO, but it was brought up and I gave information about the pole and who it belongs to , to be checked into first, as a last resort I might do it, it sounds like it IS the OP's last resort.
I have seen plenty of poles rot out, however they do last quite a long tme.
We replace poles as they rot, I started placing them 18 years ago and don't recall ever going out on one that has rotten in that time. (that was put in , in that time frame.)
Plain and simple, if it's not a good solid pole, they won't mount it, furthermore, why can't they mount a pole next to the telephone pole ?
btw, there are EASY ways to know who the pole belongs to, read the tag on it, it's about 6 ft high from the ground and it will tell you who it belongs to.
