Peter when testing listening to various stations you should be mindful as to the likely incoming wave angle. I.e do not expect a very good F/B ration if the station is not low angle. Try it and see but make your judgments on EU signals not locals. 73 Clive GM3POI

Hello to the group. I installed a K9AY system last week and added four 21 foot radials on ground radials with a ground rod at the center. The antenna didn't seem to have much directivity, so today I added another four 4-ft inexpensive TV type ground rods at the ends of each of the radials. We've had some heavy rain, but tonight I am noticing excellent nulls on European stations when changing directions. The antenna is located in a wooded area, and I had assumed the ground was fairly conductive, but apparently not... would adding another set of four radials in between the existing four improve the system? I am not sure how much the change relates to the heavy rains or adding the grounds.
