Thanks Mario, this teflon cable started out with an sma connector on each end, i removed the nut and was left with a strong gold plated body which
was made to fit and soldered inside the cone with a minimal amount of teflon separating the disk, the clearcoat also acted? a bit like glue.
This was not the first discone i have made and builds on small improvements from previous models'
A quarter wavelength on 10 ghz is 6 mm so the junction is important to keep small and the rg400 cable has some flexibility.
