Amen. Last fall I decided to rework my radial system. Here on this small
city lot it's difficult, and nice long, straight, 1/4 wl radials are out of
the question. I put down 16 thirty foot radials. Not much of an effort,
and that's what I got in return; not much. This fall I expanded that radial
system. I now have 62 radials, of any and every length as dictated by the
size/shape of my property, and unquestionably, I can tell a BIG difference.
Get some wire(lots) and start putting it down. I now have around 3000 feet
of wire down, and it is well worth the effort. I have worked two Europeans
and KL7J already this fall, with 100 watts. As soon as the K9AY array is in
place & working(today) I will correct that 100 watt situation.
