I'm pretty much restricted to a maximum height of 40' for any antenna I
install on my covenant-restricted lot. I have thought about an inverted L,
but I
also wonder if I can achieve a greater effective height by using a fatter
radiating element, primarily using wires that are spread apart.
W2PM Reply: In Bill Orr's last antenna book (HF Antenna Handbook) he
features a "short fat monopole" attributed to Doug Demaw - W1FB which uses two
parallel wires separated by 1 ft with PVC pipes. That is to simulate a "fat"
conductor. This antenna is, of course, top loaded with a series inductor and
capacitance hat - altho it appears to me the physical design of that "hat" is
rather poor offering fairly low capacitance. A simple T wire per most of the
literature would be better I'd think.
