K3NG reposted one of his classic articles Things I Wish I Knew When I Was A Young Radio Artisan. Here’s a few items from the list:
With antennas, it’s not about the feet and inches (or meters), think in terms of wavelength.
Don’t worry about the orientation of a dipole when it’s less than a half wavelength above ground.
When the bands are open any goofy antenna will make contacts. People will think this makes a goofy little antenna a good antenna. Not so.
I don’t agree with everything on the list but it is still worth reading.
