Good info! I have noticed from operating in the field that I make more contacts if I lay the counterpoise along the ground. I get better signal reports from stations in the direction of the counterpoise.
I noticed from operating this weekend at an overlook that with the counterpoise over the side of the overlook going down hill at roughly 30 degrees, my contacts were clustered farther away - again in the direction of the counterpoise. I was operating on 20 and 17 with the AX1, KX3, SSB at 15 watts.

I used the AX1 as a test in WPX CW last weekend for only an hour on a picnic table. No problem ...in that time I got 13 QSOs from FN45 including FL. (10 Watts KX2, 13' counterpoise). -- After NEC simulations (0.005, 13 average ground) , we find how the gain is maximized in the direction of the counterpoise. On 20 meters, if the wire is horizontal at 4 feet height, the take-off angle is about 56 degrees. But if the wire goes down from 4 feet to the ground (15 degrees slope), the F/B is less but the take off angle is lower at 35 degrees (Image at https://i.imgur.com/XKPjM8T.jpg ) 73, Pierre VE2PID ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
