For those of us on the East > Coast, 45 degrees puts one right in the center of Europe. Could it be I tried this on 20 meters. I laid out 60 radials 250 feet long in a 45 degree sector pointed towards Europe. It produced no improvement with a 1/4 wave vertical and 2 to 3 dB improvement (to Europe only) for a 1/2 wave vertical. I also did simulations up to 1000 radials 500 feet long on NEC3-GS. Bottom line is that you cannot (practically) simulate being on the beach with ground wires. Complete details are on my web site: <> .
