Final Vertical/Delta Test

To conclude the comparison of a 1/4 wave vertical (two elevated radials) and a vertical delta loop (with 16 x ~0.5 wavelength radial groundscreen), here are this morning's results of listening to WSPR from VK3QN, long path at 14MHz:
VK3QN heard at IO73tj, 2020 April 27.  Times UT.

Overall, a median advantage to the delta of 8dB,  with peak LP signals differing at a slightly lower, 6dB advantage to the delta.
