Circa 1965, while living in Portland, I topped enough off a 110 ft Fir
tree at the property side to install a HyGain Thunderbird tri-bander.
Did the work myself when I was young. Used a prop pitch motor to turn
and selysn's for direction indication. _Mounting took some creative
thinking but it was up for many many years_. The con was that being
exposed to the winter winds the tree tended to sway at the top more than
I had thought it would, transmitting that motion to the elements. Had
two occasions where an element eventually broke from the constant
flexing back and forth. Shortening the mast helped ease the issue. Pics
and mounting method info available if interested.

Ken,
Yes, avoid the Planning Department for sure. I have lived in four different
communities and put up a tower in each and never obtained a permit!
Secondly, if I recall, someone on Tower Talk trimmed off the top of a strong
tree and was able to mount a tribander on to the tree trunk. I have a huge ash
on my lot right now that would serve well as a solid 60 foot mast!
Good luck with your project. You can do a lot with wire antennas is they are up
high or configured to develop gain such as a half-square or extended zepp.
