Neat! I like them. There are various configurations of Ts, and the most
popular, of course, has the 2 females on the 'run' and the male on the 
'branch'. One sometimes sees the male swapped with one of the females but 
those seem to cost at least 5 times as much! 

This configuration should actually make the loop into and out of any PC or 
whatever a lot tidier. The shape should cause no electrical problems.

One must realise that the male connection at the left of your diagram must
go directly on the female fitting on the tranceiver (whether built into a 
PC card, or a seperate one with an AUI cable to elsewhere), as with any Td
in connection to thinnet.

Who sells these, and how much are they?
