Beverage antenna questions
The beverage antenna seems to be an excellent mw receiving antenna.
1) Is there a reasonable minimum length? 2) The beveage is supposed to be grounded through a resistor at the far end. What type of resistor and how much ohmage? -- "The graveyards are full of indispensible men."-- Charles deGaulle |

end. What type of resistor and how much ohmage? There are several antenna books which make the same suggestion, so I have no way of citing the original source. They all sugest you take a mechanical hour timer and connect a terminating potentiomiter to the shaft of the timer, start the timer and record the noise from the antenna. Note where it reaches the minimum. A more modern possibility is to use two HT's and have one person monitor the noise, while the other adjusts the resistance. You probably could do it with a laptop, wifi and skype, but that may affect the results. Geoff. -- Geoffrey S.

See ARRL for the book. Great reading any time. Paul, KD7HB |
