Perhaps I'm missing some other factor, but a common thing in radio design is that whatever you signal source is, that's where the majority of your amplification should happen. At your signal source is where the highest SNR will be, if you put your amplifier in the middle of the cable then you'll be amplifying a much higher amount of noise, which doesn't help much on the receiver end. Again, this is all based on there not being some other reason making putting the inline amp in the middle of the run a better idea.
