For 3 stations you'll need what is known as a "passive hub".  It's 
basically 4 93ohm resisters w/one lead soldered together to form an X 
shape and the other leads each go to the center conductor of a BNC 
female end.  Then connect all the BNC shells together (usually in a 
metal box) and you have a hub. Looks like this:
 --------------------------
 |                        | 
BNC--^93ohm^-\ /-^93ohm--BNC
 |            X           |
BNC--^93Ohm--/ \-^93ohm--BNC
 |                        |
 --------------------------  <---Square Metal Box
You can hook up 4 stations to this, for more than 4 you're supposed to 
buy an "active hub".  At that point I would replace everything w/10baseT 
Ethernet!  It should work w/any coax for short distances.
