How many times do we have to tell adult amateur radio enthusiasts the necessity of matching (a warning already offered from the shadows of this thread)? So, shall we consider the merit of a total length of 3 meters in the AM band? If this discussion is so studiously avoided by those who weep away about the dearth of information, what chance does a naive student have to rummage up the details? The Rr summons up to roughly 20mOhms. Are any of the scolds going to offer the implications of this value? Are there any suggestions of using commercial tower sections to cut down on Ohmic loss? Any matching details for the massive SWR? Any hints on how to load the structure? Details for a top hat? Would the top hat consume part of that 3 meter restriction? Would a loop perform better? What dimensions? How to build the capacitors? Talk about underwhelming help.... the dark side of the net had to have it's way with the subject. The dark side is not patronizing with soothing but impotent nostrums. The topic reduces to one of two resolutions: 1. Deep consideration of many issues; 2. Buy a kit that works as advertised. One takes many here a lifetime of consideration and books are devoted to this study, the other satisfies a need. 73's Richard Clark, KB7QHC |
