Topband: Relationship Between Ground Wave and Low-Angle Radiation

Now that I think about it a bit -- I wonder if you put up a small vertical off to the side toward the W3LPL RBN and fed some power into it 
as a reference signal then fed the tower with that little vertical open and fix up switching so you could switch between the two several 
times for each reading and get a repeatable delta - then add radials and look at the new deltas if this trial worked out ?? 

Closest RBN I have on160 is KO7SS down on Mt Lemon in Tuscon (107 miles) and I have never been able to tell anything because of qsb over such short periods of time - takes me about 5 min to change the two configurations I want to compare.
