Topband: Relationship Between Ground Wave and Low-Angle Radiation

Interesting idea to be sure...Regardless of the "theoretical" answer. I 
would suggest you take daily readings (probably between 11AM and 1PM) 
for a month and log those before starting to add radials. If day in and 
day out you get variation of more than a few tenth's of a db the W3LPL 
RBN is not likely a good choice� for this project.

How many radials do you have now and� how many are you prepared to add? 
AS you get more and more radials the incremental effect of going from 4 
to 8 will be much more noticeable than going from 24 to 28
