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.

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.

i want to know ~ RHF

- If you've got the room to select a direction, why not have a series
of stakes at
- different points of azimuth and maybe a carabiner fastening setup so
the thing
- could be quickly changed depending on your preferred direction at
the time?

"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 ?
in search of the one-best answer . . . ~ RHF

- 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.
T2FD : Terminated Tilted Folded Dipole Shortwave Antenna

- It used a 9:1 balun transformer from Palomar
- (sadly they stopped making it).
-fyi- The Palomar Engineers "MLB-1" Magnetic
Longwire Balun for Shortwave {Radio} Listening
Antennas is still being made. ~$50US

-*Reception was outstanding,considering the RFI
- and other man-made noise omnipresent over here.
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.
