Antenna orientation
Hello all
I live in Northern Alberta Canada, and I am going to put up a long wire antenna. Should I orientate it in any specific direction, or just string it up ? Thanks, Jason |

Unless the antenna is 1/2 wave above a prfectly conducting ground or
counterpoise, it really won't matter because it won't be directional. -- Gregg *It's probably useful, even if it can't be SPICE'd* http://geek.scorpiorising.ca |

Behold, CW signalled from keyed 4-1000A filament:

For fractional wavelength antennas, directionality will be lost at low
heights. At one wavelength or longer, they become directioal at any height. "Gregg" wrote in message news:WmPcb.2427$uG.1407@edtnps84...

Antenna theory, and NEC modeling radically disagree with this- How many antennas do you want to see that are not 1/2 wave above a perfect ground and yet show outstanding directionality? W4OP |

since most signals will come from the south, try east-west orientation
Or have a second antenna strung up north south & switch between them to see which is best.. In article , Jason writes: Hello all I live in Northern Alberta Canada, and I am going to put up a long wire antenna. Should I orientate it in any specific direction, or just string it up ? Thanks, Jason |
