Hello, Right to the point. At HD2A we installed an Inverted L with the following dimensions: vertical portion 16m horizontal portion 26m.
The horizontal wire goes with slightly upward with with its end at 19m above the gound. The ground system - 4 x 6ft ground rods at the base - 34 x 42odd m radials on the ground No matching device is used. Fed directly with RG8 coax. The SWR was at 1.5 to 1.8 on 1.832 now it is 3:1 at the same frequency with no visible alterations to the antenna except the rain season. The question: what could cause the SWR increment? any suggestions to bring it down and keep it relatively stable. Thanks in advance, Alberto, Alex HD2A Team _________________ Topband Reflector
