Start with an Amphenol tee connector - you could use any other brand,
as long as it's male pin is threaded, to allow you to unscrew it.
Carefully back the male pin out, and cut it down (saw/knife/teeth)
so that there will be NO DIRECT CONNECTION to a barrel connector when
one is placed in the male socket. The amount of pin left sticking up
will give you some control over the amount of rf attenuation - more
pin, more coupling - less pin, less coupling - and you leave the barrel
in place - this is your tap point. These can be used for your rf sampling
needs in a lot of instances, so they's very handy to have. Good luck...
