In 1979, after a number of years off the air, I rolled some old radio gear
out of moth balls and set up a station.  Because I had to deal with a
high-voltage power line, I was unable to use a 60-foot maple tree for an
antenna support.  As a temporary fix, I thought (until I could do something
more permanent), I decided to put up the ARRL 40-foot mast on the back of my
garage.  One of the peaks of my house was about 70 feet away, so I put a
10-foot Radio Shack mast on it, providing a height of approximately 35 feet.

The events of parenting, a tumultuous job situation, and home handyman
projects pushed themselves to the top of my priority list, and I found that
an opportunity to improve upon my temporary mast never presented itself.
Meanwhile, my two-by-four servant faithfully supported an 80-meter
center-fed zepp and later, a 40-meter delta loop fed with open wire, both
with the help of the house-mounted mast.  That wooden mast swayed and shook
in Minnesota blizzards, and on more then one occasion I stood in an upstairs
window and watched the north wind attack it, believing that at any moment it
would snap and fly away.  But it never did.  I think my rope guys were tight
enough to hold it up but forgiving enough to let it stretch.  Anyway, 10
years after I raised it, I finally took it down.  I had to build a new

Still busy with family, work, and school matters, I have not yet erected
another mast.  But, I have it built.  It lies in my back yard awaiting
installation.  I was inspecting the garage and logistics earlier this
evening.  I plan to have it in service for the winter.  It is remarkably
simple. It is the sort of apparatus that I think of when I think of amateur
radio--inexpensive, ugly, but effective.  I'm sure it is so for many of us.
