Beverag antenna
Can anyone direct me to webpages that discuss the design and
installation of beverage antennae? |

May I point out that the beverage can be duplicated by winding in tight helix form such that it can be rotated on a tower.When made in garbage can shape the bottom acts as a reflector. This provides multi polarity reception. Wire used can be zip cord or multi ribbon wire. The next step up from this design is if one adds electrically connected vertical wires so that it emulates inter woven wire (insect wire) which thus becomes a Faraday shield and is sensitive to all polarities. The helical wound beverage falls short by one polarity and short of a Faraday shield as the longitudinal spacing between the wound wires allows for wavelength penetration between them. Gains is in the same order as two FW radiators in equilibrium and both resonant as described yesterday on this newsgroup.Both of these designs may be placed close to the ground as with the beverage and may also be tilted in the vertical plane for maximum advantage. |
