The RF rated doorknobs usually have silver plated terminals and have a
dielectric designed for very low inductance and very high Q factor whereas
the doorknobs from TV sets are only designed as filters and do not operate
on RF currents hence the much less expensive dielectrics.  Design and cost
factors become the major factors.
