Summary

I stood on the shoulders of ReallyBigTeeth and Andrew McNeil (https://www.youtube.com/watch?v=TanbyHBKrvU) and adapted the design a bit:

  • made "step-wise tapered" guides so that the element can only positioned the optimal way
  • the parasitic elements have different size mounting holes to fit only at one position on the guides: "fool proof" ;)
  • added a reflector made of aluminium foil clamped in-between 2 back elements
  • back cover allows for tri-pod mount
  • used 2.5mm2 copper wire (1.8mm dia)
  • added the ipt files for own customisation
  • added lots of detailed pictures to help the assembly

This design can result into an (see foto) SWR of 1.029 on channel 6 (2437MHz).
I could not measure the gain as it maxed out my equipment :)

This is a neat little powerful antenna. Overall approx. size: 14 L x 11 W x 5.5cm H.
