I found my small camera and Had some pictures of when I built my G5RV.
This is the center insulator of my G5RV. I designed this using Autocad so it can used as a diople or inverted “V”. I will post the DXF later on if there is any interest.
I had a piece of Lexan (Plexiglass). I was cut using a CNC 4000w laser. I know many people do not have access to a cutting laser so I saw and drill press will do just as well. I then heated the edges with a blow torch just to clean up the piece and get rid of any sharp corners.
Here is the G5RV Half done. I used 12ga stranded 300ohm twin lead wire. I prefer stranded wire even though it cost a little more than the solid cord. After whipping around in the wind I would be afraid that the solid core would break in places and render the antenna useless. I also used 12ga stranded wire for the antenna. I managed to get 500ft of it but it was insulated so I spent a couple of hours stripping 100+ ft of copper wire.
I know it’s hard to make out but it’s done and in the tree. I was using a g5rv jr. kit that I bought before and this antenna took up the entire length from my house to the tree with a couple of inches to spare. It’s 40 ft high up and after months and hundreds of contacts later. It’s still performing well.
Any chance of the files for the insulator? Or even just a drawing with dimensions?
