Re: Long wire AM aerial - directional?
Far-field electromagnetic waves tend to have the electric field at right angles to the direction of propagation. So if you're using the electric field to drive AC in the wire then presumably you want the wire broadside on to the direction between you and the transmitter. Conversely if the wire happens, unluckily, to be pointing directly towards the transmitter won't it struggle to have any current at all induced in it ?
