When base-mounting a loading coil (inductor) on a shortened monopole vertical, is there a preferred method for the physical placement of the coil? Is it better to orient the coil in the vertical axis, horizontal axis; very close to the radiator element or a number of feet away; positioned close to ground level or elevated (such as on a mounting post ~ 3 feet above ground)? Assume freq = 1.83 mHz; H = 70 feet aluminum; soil = average to good; small capacitive hat (spokes, 5’ diameter). thanks, 73, Rich, K3VAT _________________ Topband Reflector Archives - http://www.contesting.com/_topband |
