Default 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.

Could you direct me to a source for this theory?

Thanks,

Many people will be real disapointed that their Beverage really doesn't work
after all, eh?

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

Let's let him have a wee frustration, then we'll tell him to terminate the
far end with a 600 ohm resistor ;-)

For fractional wavelength antennas, directionality will be lost at low
heights. At one wavelength or longer, they become directioal at any height.

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?

Phased arrays can be made directional. We are talking longwires here.

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..
