So the BA Recepter has separate AM & FM Antenna Inputs ?

Yes! The FM antenna connector is a 75ohm F style and
the AM antenna connector is a pair of wire clips(?) like
you would see on speaker cabinets.

B.A. web site has a link for the Recepter with all the details.
You can purchase a Recepter at Best Buy which has a generous
return policy. So give one a spin.
