Putting Terminators on BNC T's will unbalance the trunk cable, cause signal
reflections, and attenuate the signal. Terminators should only be used at
the end of trunk cables.
If multiple terminators are placed on T's they form 50 ohm resistors
connected in parallel and will present to the cable a very low impedance,
effectivily shorting the cable.

A NIC coax connector connected to a bnc T presents a high impedance to the
trunk cable minimizing any disturbance to the electrical properties of the
trunk cable.
It is not necessary to have a NIC connected to a tee. You can remove a
workstation from a trunk cable without affecting the network by removing the
tee from the NIC. If you break the trunk portion of the BNC T, you will
bring the network down.
