I suggest you join both posts together, otherwise the reactance of the T1 
secondary (hi-Z side of reverse direction xfmr) will be in series with the 
beverage if primary disconnected.
Shorting or loading T1 primary (low-z coax side) will also work, enabling 
you to use just one post, but easier just to short the two posts together 
for the single wire.
