Don's antenna ramblings

The last post on the 15 meter antenna brought up the radiation angle and the height of the ionosphere. I thought I would switch gears here...

The higher bands (15 and 10 meters) are now starting to open for DX. If you do not have an antenna for these bands yet, I suggest building a...

I have recommended that horizontal antennas be a half wave above ground for best performance. For the lower bands, this states to be a probl...

The concept of impedance is very important in antennas and transmission lines. Remember that impedance is the ratio of voltage to current. ...

Antennas do not have to be resonant to work well, but it does make feeding them a little less complicated in general. When learning the bas...

I may be repeating a few things as we go along, but I think the important principles of radio and antenna theory need to be reinforced. I h...

In a resonant half wave dipole, the voltage and current enter the antenna at the center, travel to the ends and get reflected. The current ...
