Title: dipole orientation
Post by: KK4MYT on January 01, 2013, 04:42:21 PM
If you have room which way would you run a dipole.
I am thinking best for me in VA is to run it. North south.
Or does it matter. Maybe two one n/s and the other e/w

It depends on the band, antenna height and if you want to work the US only or you are a DXer.

Experiment.  Try it several different ways and see how they compare.

My 33' rotatable dipole fed with 300 ohm ladder-line works well on 5 bands, 20m-10m, and the rotor for such is inexpensive. Or you could rotate it by hand until you are satisfied with the coverage.

If it's up less than 1/2 wavelength, it probably won't make much difference. Probably more significant than height, though, is that if the antenna is inside the house, the pattern will be distorted by wiring, plumbing, and other conductive stuff.

That sounds like a great antenna.  How directional do you find it to be?

At 40' high, there's a 2-3 S-unit difference broadside vs off the ends. (7-9 dBi maximum gain according to EZNEC.) Super simple to install.
