Re: NOISE ADVANTAGE OF LONG WIRE ANTENNA FAR END TERMINATION

BEVERAGE ANTENNA TERMINATION - 2 - THE FAR END TERMINATIG RESISTOR Theory and software modelling place the impedance of the Beverage antenna at a value between 500 and 600 Ohm, depending on wire altitude over ground and soil characteristics. The previously uploaded test results, done with 560 Ohm a...

Re: NOISE ADVANTAGE OF LONG WIRE ANTENNA FAR END TERMINATION

BEVERAGE ANTENNA TERMINATION - 1 Contrary to general opinion, long wire antennas in general and Beverage antennas in particular are not easy to optimise, because their simple form is deceiving. The general optimistic belief is that, once you have the wire to spool out and the land to lay it on, the...

Re: NOISE ADVANTAGE OF LONG WIRE ANTENNA FAR END TERMINATION

At present I am collecting antenna noise data for the next two weeks, in order to compare with previous uploaded data. I have decided to proceed in this fashion, as data collected over only a few days could lead one to wrong conclusions. In the meantime I have done Network Analyser measurements on t...
