Ham Radio-Experimenting with a loop antenna on the ground receiving antenna.

  If you are plagued by high background noise levels at your location, please try this loop-on-ground receiving antenna from Kevin Loughin (KB9RLW). According to Kevin, this loop antenna eliminated much of the RF noise at his location.   You can build this antenna very cheaply using locally available materials.

Here are a few comments from Kevin (KB9RLW). spent some time exploring this low noise receiving antenna concept and tried a variation on it by lifting it slightly off the ground.

Building a multi-band dipole

Image
  One of the easiest and least expensive dipole antennas available is the "classic" fan dipole.   If you're like Bob (KK4IV) in this video, most of the parts can be found in your "junk box" or at the nearest hardware store or building supply outlet. In this instance, Bob designed, built, and tested a multi-ban fan dipole covering the 40, 20, 17, and 10 meter amateur radio bands.  No antenna "tuner" is needed. This antenna uses parallel dipoles cut for each band and a single length of coaxial cable for a feed line.  The antenna is a simple project which delivers excellent results.

Here are some comments from Bob (KK4IV): I built a multiband dipole that will work 40, 20, 17, and 10 meters for ham radio. An easy project I was able to tackle in one day. Calculat...
