I bought a CCrane ferrite AM antenna... I really like the results Ive gotten. I Ran the antenna element out a window, and got pretty good reception across the band. The manual says I can get better reception if I ground the antenna. It has a ground nut. Can I attach a wire from this to the steel security bars on the window, or will this cause the house to spontaneously combust the next time we get thunder? Will this result in an effective ground?
