Question about building the "Cheap" Antenna by WA5VJB
I am working on some a couple of the "Cheap" antennas by WA5VJB, that have been talked about on here. I am building these for Field Day and th use for some moble work on AO-51 & AO-27 after that. My question is this, Is the "J" /DE element centered in line with the others or is just the long side in line? My guess is the long side but thought it better to ask.
Thanks Marv N0FJP

Hi Marv - See the link below. The element is centered at the point midway between the free end and the most outward part of the bend where the matching length heads back toward the feedpoint.
That's about as complicated as I can put it - hi...

I made the element (the long part) in the same plane as the other elements. I figure the short part is the matching section.

Thanks Tom, I have it all made. I may need to do a Rev. 1.2 on it. I have the DE centered. I thought about it and just drilled the holes. It will be easy to change if I don't like to outcome. I'm going to try and get it on an antenna checker this weekend to see how it tunes up and where.
