I have not seen a length mentioned for the inverted L, so thought I would note that by making the inverted L longer than a quarter wave moves the high current portion up the vertical. I had good luck with an inverted L about 3/8 wave long. By good luck I mean DXCC plus some on 160. I still am trying to improve. In any event feeding the inverted L with a series capacitor made tuning a breeze. By going longer than a quarter wave made the feed point inductive and raised the R value closer to 50. 73, Don N4DJ Sent from my iPhone _________________ Topband Reflector |
