OK, so that wasn't very readable. Sorry about that.
Next step, I took the two ends from being held down at their own length with tent stakes and I ran them both out to fence posts. One side was about 20ft away and the other was probably 40ft and slightly uphill. Both posts about 4ft high. With that I took the following readings.
17m -- 9.1
20m -- 12.1
30m -- 4.9
40m -- 8.9
80m -- 16.3
A little improvement, except on 30m, and still not very good. So I got to thinking.... where was my genuine BD certified UNUN? I put it in line and ran the test again.
17m -- 10.6
20m -- 3.2
30m -- 1.3
40m -- 13.9
80m -- 12.8
Not much difference on 17m, but I'd call both 20m and 30m useable! I don't have any other tricks up my sleeve for this evening, But it has been a learning experience.
