Default Re: Long wire AM aerial - directional?

A directional, long-wire receiving antenna for LF and MF would be the Beverage.

It consists of a horizontal wire, one-half to several wavelengths long, 10 to 20 feet above the ground and pointing in the direction of the station.

At the far end end, it is terminated to ground using a 450 Ω resistor to match the characteristic impedance of the antenna.

At the other end it is connected to the receiver using a transmission line and a a 9:1 transformer to match the antenna to line.
