How to ground an antenna Antenna RF ground Antenna ground plane Knowing how to ground or earth an antenna system can be a key factor in the operation of some antennas.Knowing how to ground an antenna properly can make significant improvements to its performance, whereas a poor gro...
You usemicrophonesto capture thesoundsof people's voices and turn them into electricalenergy. You take thatelectricityand, loosely speaking, make it flow along a tall metal antenna (boosting it in power many times so it will travel just as far as you need into the world). As the electrons...
Internal TV antennas might be a simple set top antenna. These antennas tend to be relatively smal and by their very nature they do not have much gain, although some have an internal pre-amplifier to make up for the lower strength signals that are received. However the amplifier can fully ...
If those methods don’t fix things, the problem could be an over-the-air (OTA) antenna or a cable-TV coax cable that has its own path to ground. I’ve received some pretty annoying shocks when handling coax signal splitters. Normally—because of the isolation...
The distance at which cameras could be detected was increased almost by four times by using a resonant coil wound on a ferrite rod. Details on the construction of this coil can be found in Appendix B. Table 2 lists the distances at which various devices could be detected. As a pickup ...
away from each other, is fairly simple to make and can be designed vertically at 1/4 the specified wavelength, but it will not be as effective of a receiver as other models. A parabolic antenna uses a dish, and while it may be effective, you may not have the supplies to create one....
