[Lowfer] Sloper antenna question

Gentlemen:

Unfortunately for me, I live in a rather noisy location for radio reception which is very frustrating. I have always desired to be able to hear better than talk.On the best day, my S-meter reading on 10 meters runs an S-3 on SSB, the lower in frequency of course, the higher the reading goes. I am surrounded by power lines on 2 sides of my property, and I'm butted right up against the adjoining propertys " Woods ". I have one side that is open, and it runs fortunately in an eastward direction.

My main interests are for 160 meters, and below, hoping to lower my noise.
I have been reading about the sloper antenna recently, considering it mainly for reception. I can't put up a horizontal loop. The OCF Windom I currently use seems to do very well, but is there an antenna that will receive good, with a lower noise pickup from mostly manmade noise. I'm not wanting to try anything that requires power, sticking with the simple wire type antennas. I don't have the room though to run a beverage.

Here's the antenna I have the interest in, and hopefully some of you guys have had experience with it, " Pro or Con ".... I saw a sloper design that was intended for space restricted users. A 1/2 wavelength of wire, with half of it linearily wound on a PVC pipe, and the other half stretched out in the desired direction and tied off. Many combination are possible in its orientation, such as; the coil section horiz. and wire horiz.;;; coil and wire at a 45 degree angle, ;;; coil horiz. and wire at 45 degrees. Coil vert. and wire horiz. The one that intrigues me the most though, is with the coiled section mounted vertically, and the wire half sloping at a 45, or whatever degree angle. One of the MANY websites I visited, stated that in this arrangement, the antenna would exhibit both vertical, and  slightly horizontal characteristics...

Has anyone tried this type of antenna, in any configuration ?? and what was your experience with it. Again, mainly for receive, and hoping to lower my noise level on 160 meters and below. If this is even worth trying; my thoughts were to build it for a full wavelength on 160 meters, and it should receive OK at 600 meters, and hopefully decent below that. Mounting height will most likely be around 20 feet AGL, and slope down to about 8 feet AGL.

Thank you for your time reading this, and for any replies.
