Important Upgrade (Oct. 5, 2014)
The shorting bars shown above
have now been replaced with the ones below.
This is a two piece compression type
with 8-32 stainless steel machine screws and nylon insert locknuts.
The hole radius is the same as the rods which ensures continuous
surface contact and the chances of the bars loosening is almost
bars are held in a fixture and drilled with a center cutting end
mill chucked in an R8 collet. The end mill makes a more precision
bore than a standard drill bit held by a drill chuck.
I do not have time to take
new antenna pictures at this time so if you order an antenna it
will be shipped with these new shorting bars.
