Yagi antenna design question
Wes wrote:
op cit. I'm not "folding a portion of the element." If you subscribe to the idea that part of the antenna can be "folded into" the feeder and that by selecting the right feeder length you can "lengthen the antenna" (as shown in a lot of old ARRL literature) then I have a new limited space antenna for you. It's a one foot long radiator with a variable length feeder (a la Cecil) that "makes up" the missing antenna length. Why didn't I think of that? The SWR on the ladder line on 40m would only be 47,000,000:1 and the feedpoint impedance would be 10 micro-ohms at system resonance. -- 73, Cecil http://www.w5dxp.com |
