THIS IS A NEW CHAPTER ON MY WEB.
Please be patient while I move some of the pages around and create a couple of new ones.
Basically there are 4 different kinds of loop antennas interesting to the amateur radio operator:
- VERTICAL LOOP
- HORIZONTAL LOOP
- SMALL TRANSMITTING LOOP
- SMALL RECEIVING LOOP
- Vertical Loops are loops mounted in a vertical plane, perpindicular to the earth.
- Vertical loops may be a single stand-alone loop (mono-loop), or they may be one or elements of a directional antenna, such as a Quad.
- There are two types of Vertical Loops:
- Horizontally polarized loops
- Vertically polarized loops
- Whether a loop is horizontally or vertically polarized depends on where you attach the feedline to it.
- Vertically polarized loops work better for DX whenever the antenna must be mounted closer to the ground. In addition to having a lower angle of radiation than the horizontally polarized loop, they also reduce the local QRM (stations within about 500 miles) by a couple of S-Units.
- Horizontally polarized loops are typically quieter (on receive) than vertically polarized loops and if you can mount them high enough, they would be preferable even for DX.
- Horizontally polarized loops typically product a stronger signal out to about 500 miles or so.
- Horizontal Loops are loops mounted in a horizontal plane, parallel to the earth.
- These are typically just one single loop in the horizontal plane.
- They are generally located close to the ground (about 1/8 to 1/4 wavelength high).
- Although they are known as "Cloud Burners", meaning they radiate alot of RF straight up, they can also be good dx antennas.
