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

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.

Where would you place 'Point' the Bottom-Far-End for the
best DXing ? [ N ? E ? W ? S ? ] & WHY ?

Given that it is claimed that in general the Sloper produces
it's best reception in the direction of the Bottom-Far-End.

Coax Cable to the Feed-Point and Top-End-Feed-Point.

Thinking of Rigging a Par Electronics EF-SWL Antenna
as a Sloper or buying one of these Pre-Make Slopers.

"OB",

Given that I am on the West Coast of the USA
Northern California Sierra Foothills.

1 - Receive Trans Pacific Shortwave strongly from
New Zealand & Australia & Singapore & China &
Japan & Russian Far-East

2 - Receive Shortwave from the East Coast of the
USA very good.

3 - Receive Shortwave from South {Latin} America good.

4 - Do NOT receive Shortwave from Europe well.

5 - Do NOT receive Shortwave from Middle-East
Region well at all.

6 - Do NOT receive Shortwave from Africa well.

7 - Do NOT receive Shortwave from India etc well.

What Diriection would you 'Point' the Bottom-End of
a Sloper Antenna for the best DXing from : Europe ?
Middle-East ? Africa ? and India ?

? N ? E ? W ? S ? and WHY ?

Though I have not been living on the West coast, nevertheless one
cannot expect strong signals from certain areas over there . In
dealing with such unstable propagation as we had in the last few years
a single antenna may not be sufficient and re-orienting it may not be
enough. Over here,in NYC I tried using a commercially made sloper
antenna in the early 90's and didn't see it performing substantially
better than a simple random length wire. That applies only to my
location,that is. . . The best antenna I EVER had was a home-made
T2FD. Much quieter,had some gain and it was absolutely
omnidirectional as far as I know. It used a 9:1 balun transformer from
Palomar (sadly they stopped making it). Reception was
outstanding,considering the RFI and other man-made noise omnipresent
over here.

-fyi- The Palomar Engineers "MLB-1" Magnetic
Longwire Balun for Shortwave {Radio} Listening
Antennas is still being made. ~$50US

Several years ago I bought a used Wellbrook [UK]
Universal Magnetic Balun UMB T2FD and never
http://www.wellbrook.uk.com/UMBT2FD.html
got around to using it. IIRC it is somewhere down
in sub-basement # 3 -but- like I bought it and
stuck it on a shelf and don't think that I have seen
it in years. Heck I have not been down to check
out sub-basement # 3 in years . . . hope that the
sump pumps are still working . . . got to add that
to my To-Do List on the next trip to Alameda, CA.

I already have two SWL Antennas up here in
Twain Harte, CA -but- neither seems bring in
Europe; the Middle-East; Africa and India.

Have you generated a Great Circle map centered on your location? That
would be step one.
