GRJ! I thought about this too.... but once I started draw a schematic it stoped making sense. The antennas on the TIU and remote have to both transmit and receive. So which way does the amplifier point? If it points outwards then it can transmit but not receive. If it points inwards it can receive but not transmit. If you put amplifiers pointing both ways its an oscillator.
Pretty sure some of these have intelligent routing that detects when you're keying transmit and switches modes. I know the WiFi model I used for my old house even stated that in the documentation. I use this specific model, the one I previously listed was a newer model, but Amazon automatically linked my order history to the new model. This has no connection to the internal WiFi logic in the router, it just figures out the direction and switches automatically from transmit to receive.
A key operating characteristic is...
Operation mode: Bi-directional, half-duplex, time division duplex
I'm pretty sure many of the 900mhz buffers would have similar logic, though I haven't actually used them. In any case, they can't really transmit and receive on the same antenna without having a significant frequency difference between the transmit and receive frequencies. This option is certainly worth a look if the hi-gain 900mhz antenna doesn't do the trick.
