Every active ham uses an antenna. But how many hams can say that they really understand what happens when they apply RF to their antenna? The RF signal somehow leaves their antenna and is picked up by an antenna on the other end of a QSO, but to many hams this is a mysterious process.

  Did you know that deliberately mismatching an antenna to it's feed line can increase its SWR bandwidth? Here's how it works
  Put simply, the performance of a DX antenna needs to be measured under DX conditions.

• Electromagnetic Radiation Explained
  One of the least understood phenomena in electrical engineering is the idea that electric and magnetic fields appear to leave a radio transmitting antenna to form what we know as radio waves.
