Currently I am living 1/2 of a amateur radio buff's dream. I work for the largest antenna tower manufacturer in the world but my wife won't let me put up one in the back yard. Such is life...

If you ever need a seriously heavy duty tower... http://www.pirod.com

Incidently, ?DaveBunte uses Pi-Rod towers at both work and home. Here is a quote I found in google groups. -- ?WardCunningham

In the broadcast biz (my field), I have seen lots of guyed towers...we have four of them here and all have single point bases that can pivot. By allowing the tower to swivel a bit in extreme condx, you allow the force to be shared by all the guys, rather than being concentrated at the point the base would otherwise enter the concrete. Our towers are Pi-Rod...a company that uses solid steel for the legs, rather than hollow tube...(I have one of their freestanding towers at 100') and they also recommend against securing the base in concrete, even though their style of construction might be able to take it.

By the way, another strong reason to not bury a section in the concrete is that it is then much more difficult to control moisture in a hollow-leg tower. I have seen them rusted through so badly you would not dare climb 20' up.
