Greetings. I'm getting ready to start my first attempt at a 1/4 wave vertical
 for 40 meters. (Maybe 80m later on.) Perhaps someone could give a few
pointers.
I'm thinking of 1" copper pipe for the first 20' and 1/2" or 3/4" for the
remainder. I could "guy/dacron" it at the 20' mark if it turns out to be
necessary. Is this size copper a bad idea? (It will have at least 4,
probably 8 or more elevated radials (over pretty good ground).) Then, how do
I tell how long to make it? For a typical dipole, 468 / 7.150 gives me a
length of 32' 9", but I know the diameter of the pipe will affect this  so
how do I compute an good length? (Good guesses are appreciated, too!)
And last questions... what would be a good way to hook the coax to the base of
the 1" pipe and radials?
Thanks & 73,
Dave N0RQ
