Hello;
I have to share a bit of this and perhaps vent a little.  Feel free to hit delete.  I have been chatting with my local radio club that meets within walking distance for nine months of the year.  They came over last fall looked my happy home over opened an antenna box and rummaged a bit and said they would be in touch.  At the time we had the "best antennas go up in winter" chat.  Come winter we decided it was to cold and they opted to wait till spring.  Now that it hit 80 here for a day I talked with the president a bit last meeting.  I got a call from one of the officers the other day on my voice mail.  I made the mistake of getting a bit excited and ready to get going.  I called this trusty officer back and discovered he primarily wanted to put me in touch with arrl to get the local power authority to move my neighbors power lines.  I had decided long ago that I was reluctant to get into that battle.  I was also told that if the vertical I am considering is on the roof of my one story house the power lines are no longer an issue.  The original intent was a ground mount.
The bottom line was that I was informed that if I am planning on putting the antenna on the roof of this single story home I should have it professionally installed.  The obvious next question was where do I find these professional installers and he had no idea.
If some of you have the good fortune to have some eager willing to help local hams, take time to show them your appreciation.
Richard
