It really depends on the frequency you're trying to receive. In
general, an antenna height of 1/2 wavelength above ground is something
to aim for. At 14 MHz that's about 33 feet; at 7 MHz it's about 66
feet.

Then that may be the difference, the height. I very rarely, like maybe
not at all, venture even over 9MHz. The main band on shortwave I
listen to is the 60 and 40 meter band, so if I went another 10ft it
should be better, correct?

How high is it now? You mentioned various heights from 25 feet to 55
feet. Raising it from 25 feet to 35 feet might make a noticeable
difference. Going from 55 to 65 feet might not be worth the trouble
(except to get your ant further from man-made noise sources).

- The sloper is now at 55ft.
- I thought that one post said that if it was at 65ft.
- that would be optimal for 7 MHz.
- All I basically monitor is from the 60 meter band
- to 7MHz. Not that I don't at times go outside those.
- I have another long length of wire for the lower bands
- if I want.

BCB LzS / BCG,

OK the 'peak' of the Alpha Delta DX-SWL
Shortwave Sloper Antenna is at 55-Feet.

Question - What is the FAR-END [Bottom]
Height in Feet :

[ ] Basically "Flat" at 55-Feet too ?

[ ] Slightly Sloping at 40~45-Feet ?

[ ] Sloping at 33~38-Feet ?

[ ] Real Sloping at 25~30-Feet ? {Roughly 45*}

[ ] Getting Nearly Vertical at 15-Feet or less ?

NOTE that the Sloper {Sloping} Leg is only 60 Feet Long.
