What is the Best Direction to 'Point' a Sloper Antenna for DX ?

Given an area where you could locate a Sloper Antenna
with a Tall Mounting Pole "Top-End-Feed-Point' and the
ability to move the Bottom-Far-End around the full circle
of 360 Degrees.

- - [ N ? E ? W ? S ? ] & WHY ?

- Top-fed slopers in an open space are essentially
- omnidirectional. Most of the radiation happens at
- the feed point. The slantwire and the support
- structure form a low Q mass that also radiates,
- equally well in all directions.

Dave - Tha is All very True for Transmitting Antennas
that are 'Radiating' Power from them; be it 1W, 10W,
100W, 1KW . . .

But a Receiving Antenna collecting 'free' Radiated
Power from the Either in the order of mW ~ nW :
The Direction {lay of the wire}; Ssize {length of the
wire}; and Position {angle of the wire} can each and
all contribute to the 'general direction' that the Wire
will gather 'more' RF Signals from : Given that some
RF Signals will be Radiating from a Point-Source
and mostly Traveling a specific Path between the
originating Point-Source and the specific Location
of the Receiving Antenna.

Reciprocity says that the same rules apply to receiving.

Here's the listen only version of the Alpha Delta. It is top fed for
best performance as well.
