don't believe in that magic numbers stuff.Numbers always start with 0 cuhulin ---------------------- The irony was clearly lost..... I was going to show how to calculate a 1/4 wavelenght dipole, decided it would be a waste. Just go for as long a wire as you can put in the air. Higher is better. Longer is better. Stay way from power poles and do NOT run your antenna under a power line. Anything over 200' starts to get directional in the direction the wire is running. Wire can zig zag all over the place and still be effetive. A 50~75' wire works pretty darn well. A 1000' wire works well also. And a 666' wire would also be good. :-) And for radios (300/F)/4 is the MAGIC number. A good number to be able to generate. Even moreso if you ever wish to transmit. Terry |

It is said in the Scrolls of Skellus that a wire antenna 666 feet long will receive transmissions from hell. You gotta schematic for that? g 73, Steve Lawrence Burnsville, Minnesota Every moment of a human life is an act of worship. Coincidence is God's way of being anonymous. |

![]() Try to set up as long a wire antenna as possible; way over 100 feet most Dxpeditions use 800 foot + wire antennas.. Set it up so the broad end ( length) points toward what your trying to pick up signals from; If you r in the south, and want to pick up stuff from the north, set the antenna up in an east- west line. Keep it away from electrical equipment, electrical lines. Disconnect it when not in use ( Lightning) after you have it set up, turn on your radio to a frequency with no signal nearby but one far away you want to try picking up Now move the antenna wire closer to the radio.. Poke at it.. Should be fun |

No... if you want to pick up stuff from the north one would wish to have the length of the antenna running south to north. This would be true of a long Beverage type of antenna.
