If the signal strength is -52dBm into 75 ohms, then that's a voltage level
of 687uV which is a bit low.

My Sony ST-S311 tuner gives the signal strength in dBf, which I
believe is relative to one femtowatt (10E-15W). If my calculations are
correct, then 52dBf would equate to 109uV, which is not very good at
all.

The OP's manual should hopefully define the measurement units used.
