I’ve been thinking about building a 3 element triangle receive only array for 160m I have been reading ON4UN’s book trying to get ideas on how to go about building what I want. One thing that I’m having problems understanding is the delay line that is switched between each antenna. I have gone through the formulas to calculate the length of the desired delay line but, how do I go about measuring the length of the delay line? What type of test gear would I need? I have a AA-200 antenna analyzer but that’s it. Sorry about my ignorance on this subject but, I have never done anything like this before. At 160m how accurate does the length of the delay line really have to be? It seems like ¼ wave matching sections can be +- a few feet and still work just fine. So before I waste a bunch of coax I thought I would ask first. 73 Dave _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
