How much of a detrimental effect would the steel 6 foot above ground, concreted in support post a couple or three inches away from it have? Specifically I am toying with doing this to use it on LF 136kHz with my horizontal quad loop as the capacitive "top hat" to gain as much vertical height for the radiating element as possible, right now the mast has a long insulated line to the corner of my horizontal quad loop with the vertical some way from the mast, although today to minimise sag from having the vertical some distance away I moved it nearer the mast. By so doing I have gained maybe another 8 feet of height. Thanks. Thanks -- Best regards, Chris 2E0ILY mailto:dead.fets@gmail.com
