or is it enough to "fatten" the vertical (radiating) section ? How much BW will 3" diameter spacers give me?
About 16 years ago I modified an ordinary inverted L (with c60 feet vertical) using 4 vertical #14 wires spaced in a one-foot square--hoping to broaden the TX band width. No sign of improved bandwidth could be observed! I was using the same groundplane of thirty-six 65-foot-long wires about 2 inches into the soil and the same horizontal loading-wire.
Then I built a 86 foot tall, T-topped vertical with a 4-wire gull-wing groundplane at 20 feet which I'm still using. Its bandwidth is a little better than the L had.
