![]() "Richard Fry" wrote So back to rote: The physical size in relation to wavelength dominates launch characteristics, NOT electrical length. __________________ I don't know who wrote your rote, but here is part of what Terman says on this topic in his Radio Engineer's Handbook, p 795, referring to vertical radiators driven against ground: "Top loading has the same effect on the field distribution in a vertical plane as a greater height. Thus an antenna for which H = 0.45 lambda can by suitable top loading be made to have a field distribution in the vertical plane that is substantially the same as for a vertical wire of H = 0.6 lambda." ============================= No, it doesn't ! But you could stretch "substantial" (a non-engineering term) a bit more. You have been warned once before about quoting Terman as the Bible. (smiley) ---- Reg. |
