I am about to erect a new antenna. Its a dipole for 20mts. Whats the best orientation do members consider for 'general use' for someone who lives in the north west of England. (Between Manchester and Liverpool.)
I shall call the 2 ends of the dipole 'Nose' and 'Tail' ....... Yes I know a dipole has neither as its balanced, but it saves confusion. (imagine its a snake )
So what do you all think is best for me for the 'nose-N-tail' to point. I have 3 options available to me. (due to available supports to string ends to.)
North - South (nose-tail)
NNW - SSE (nt)
WWN - EES (nt)
Many thanks, Nick
i think your going to have problems with neighbors with a snake in the air!
use all of them! start off in one, then after 6 months move to the next to see how you find new stations etc. or your signal strength working the old
Nick, Unless you elevate your dipole at least 1/4 wavelength above ground, it will exhibit little (or at least multiple lobe) directivity. A dipole is directive broadside to the array. If you want to talk to North America for example, (NW) the wires should run roughly southwest to north east, giving you a NW broadside pattern.
(I see that I "doubled with AC0FP, who said about the same thing concerning height)

To whom/where do you want to make contacts?

All this WWN busines has me confused, the best position, assuming you live in Warrington, is to have the tail pointing towards Frodsham and the head towards Bolton. You can then chat with Alberto and Klaus most of the day and Bob in New York when he pops in, and then hope for a goodly supply of sunspots.
Just wanted to ask for some clarification. When discussing height, is that height above land or height to any surface? Meaning if on a roof, do you count the feet above ground or the feet above the roof?
