Hello OMs Topbbanders As I'm planning to put up inverted L antenna for next season i will face the matching vs bandwidth struggle I know there is a cure for short vertical section and low impedance (with reasonable radial system) and I already tested some extended horizontal section and matching capacitor in the feeedpoint
However i was considering some other impedance matching methods and came across DK7ZB matching transformers. For example to get good match for 28Ohm yagi there is 1/4 wave 75Ohm parallel feedlines transformer used with good, wideband match. Since short vertical inv L over reasonable ground should have roughly 20 OHm impedance that could work here as well. Sure it is 2 x quarter wave 75 OHM coax (shortened by VF) but is there any wideband "gain" for such feeding method? It would be still easier than switching remotely some caps each 10kHz or something. Is there anybody who tried this one? Thanks Tom sp5xo _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
