Hello Sanghunter:
The 36 feet long vertical radiator element would not be able to be supported by itself, guy wires would have to be used.
And you would want to use aluminum tubing, as its much lighter. The differance between copper and aluminum is insigificant as far as antenna performance goes.
The matching circuit would be have to be worked, but can be done.
After a antenna is longer than 5/8 a wavelength, it has the energy in patterns shooting up into the sky. But since I have never tested one, it might be a science project to see how one works.
What you might think about is a TWO 5/8 wavelength vertical radiator elements stacked on top of each other. Again (even with aluminum tubing) back to needing a guy wire for the antenna. Many VHF and UHF antennas are stacked this way.
