Power verses range?

With all things being equal, one may increase the transmitter power to overcome losses due to transmission line loss, but beware. You will also lose valuable receive signal strength at the receiver antenna terminals and this cannot be recovered. Even adding an amplifier at the receiver will amplify both noise and receive signal thereby making…

Antenna Height verses Range?

In general, higher is better in UHF antenna installations, actually in any antenna installation. Raising the antenna over nearby obstructions may make a dramatic improvement in coverage. Within reason, the greater the height the more the coverage, but this gain must be balanced against feed line losses. Typically when you double the height, you’ll increase…

Why can’t I depend on an off the shelf antenna to work well?

Let’s be realistic about the gain game many manufactures play. Any designer knows that it is not possible to accurately predict how an antenna system will perform based upon a particular unique installation, unless the antenna installations are the same. To get any kind of meaningful estimation would require more than modeling, and would require…
