Which brings up an interesting question.. What would the best impedance be for open wire line, assuming you have some sort of tuner at the feeding end, so you dont care from a drive standpoint. And a
I'm looking for a paper reference to basic trapped antenna design and performance, preferably in something like an IRE or AIEE journal (I'm sure it's pre-IEEE). I'm writing a paper and I make a refe
perfect... that's exactly the kind of thing I was looking for. https://ieeexplore.ieee.org/document/1141000 Abstract: The trap-loaded cylindrical antenna is a cylindrical antenna having one or more t
Here's an intersting one - can't find the actual paper, but it seems to be an antenna with a bunch of traps spaced in a log periodic way. I also found someone who had one with 13 wires and 39 trap
More interesting stuff.. Here's what's probably the original patent (oh for the days when a patent was only 3 pages...) https://patents.google.com/patent/US2229865A/en Here's an intersting one -
This is why FEM codes exist - the analytical expressions get you most of the way there, but then as you start to find equations for more of the interactions, pretty soon you wind up at NEC - which
"NEC does use a simplified model for the "wire" - it takes into account dielectrics and skin effect (I'm in the middle of figuring out what ZINT does, which is the core of the "resistance and induc
I love the multi blade strippers with the interchangeable adjustable cassettes. You can set them up for different kinds of coax, and when you swap, you just put in the already adjusted blade set. M
