The pictures on eBay are nice, one shows the ICs with the tuner can off. On the left hand side you can see the tuner ICs feeding the larger demodulator ICs to the right. Amongst the tuner ICs you can see small chips and transistors which will be amplifying and splitting the signal from the F-type connector to the four tuners. Usually this is so that each tuner gets the same signal strength as if it were a single tuner board, and is also isolated from the other tuners.
