Yes. Emitter, source, or cathode followers may be used, one for each
tuner to isolate the tuners from each other.

All the the bases, gates or grids can be fed from the same antennna
signal. Individual isolated signals are available at the emitters,
sources, or cathodes for the tuners.

Radio Shack or some similar supplier likely has a device such as this
with one input and multiple outputs available off the shelf that works
in the VHF TV and FM broadcast bands. Unlike the followers, it may give
you 10 dB or 20 dB gain on each output.
