Antenna Loops #off_topic


 

There have been many posts regarding end fed?antennas. I hope these posts were helpful.?

My favorite portable antenna are?various loops, either full-wave?loops,?quads, or Miniature Magnetic Loop Antennas. Why do I like loops:

  1. Because they are a closed circuit resulting in very low noise, far less than a dipole, verticle, or end-fed wire (NOTE: You can't work what you can't hear)
  2. Because the can be polarized vertically for low-angle radiation, horizontally, or even a hybrid of these
  3. Because they are easy to build and match to a 50-ohm coax
But for portable operation, nothing beats a Minature Magnetic Loop antenna. This is because it is light-weight, directional, and can literally sit on the ground and still work perfectly well!

I wrote an article about Miniature Magnetic Loop Antennas for the Elecraft.com team way back in 1999 when they were not yet so popular (i.e., I was a builder of the early K2 and beta tester for the 100 watt?linear). Check it out at?. You can build these antennas with materials from any home improvement store. I hope they inspire some antenna building from among the uBitx?building family.
