> But if you where to hold the R2 in the dishes focus, wouldn't that
increase the reception regardless of frequency? My guess is it would very
much do so, and by moving the R2 around the focal point it would be possible
to find the maximum. At the maximum the dish would be very directional with
a small beam but with the R2 out of focus the direction and beam would open
up. The question is what happens to vertical polarized signals in a dish
that normally use circular polarization?

The short answer is no.
If you want to increase the signal of a particular frequency you would 'see'
a lot more gain with just
a two element beam.
The same idea you are actually contemplating by using the dish as a
reflector, and your 'R2' as the dipole, only a lot less weedily.
Take a look at this site for more ideas on dish antennas ;
