You mean like this: I got ideas from the Rohn catalog and built a zero-pen base from big-box store angle iron bolted together for our recent ARISS QSO. Mast is 1 1/4 iron pipe threaded into a floor flange on a hinged based, braced as shown. Rubber roof mat underneath. Concrete block ballast. Held up quite nicely through a strong frontal passage with wind and heavy rain over the weekend before the contact. Observations: A 6'x6' base is very stable and wasn't too heavy by itself (under 5o lb) but hard to transport w/o use a good-size pickup truck or trailer. 14 gauge angle iron is easy to work with but not cheap at big box stores and too bendy under load if it isn't well-supported along the lengths. A thicker-gauge angle iron welded and painted would be more rugged and better for long-term use.
