i see.  stick the adapter on the T and termininator on the other side of the T.

you remember the vampire taps on think ethernet?  sam principle.  it
was coax too, but high grade stuff, who name i forget, bu you're using
RG-58 [50 ohms].  the high grade stuff had N connectors on the ends
and was used for high [UHF/SHF] freq, high power and was low loss.

iirc RG-58 losses are 3db/100m.  it's good for VHF [< 300Mhz] but
not so hot for UHF [> 300Mhz].

the high grade stuff was chosen for 1km 'rings'.

you can see i wasted/spent a lotta time with radio stuff.
