How to get an additional 7 dB gain from a dipole
The title may be misleading at first glance but I have a very good 10 meter dipole for working DX into Europe. I could sit on frequency “run” for hours at a time in a contest but South America was just not as easy at my new QTH. I put up a second dipole broadside South and switching back and forth I saw better than a 2 S-unit difference. The second dipole did indeed give me about 7 dB improvement!

For the last 10 meter contest I even put up a third temporary dipole pointed at the West Coast. Switching between the dipoles felt like turning a big 6 element Yagi that I once had on 10 meters! However it was much quicker to flip the switch than use the rotator!
