No. Most receivers have the same input impedance - about 50 ohms so you
would only need one tuner. The tuner resonates the antenna at some
frequency of interest.

Sorry there buddy, you are mistaken in that comment about resonating an
antenna. Tuners don't "resonate" anything, they simply fool a transmitter
into thinking it has a good impedance match. This is done between the

tuner
and the transmitter only, even if ridiculous impedance and reactance
actually exists on several parts of the feedline and/or antenna. In that
case, the tuner will have to dissipate a lot of heat that the antenna

system
throws back at it. When a receiver is connected to a tuner, the tuner
likewise simply balances the piece of line between itself and the receiver
and nothing else. This often improves reception, but it has no affect on

the
antenna whatsoever.

Durn it, you mean that remote tuner out in my backyard at the antenna is
just fooling my transmitter/receiver?

I think you are talking about a transmatch, commonly and mistakenly called
an antenna tuner - which has nothing to do with an antenna and, as you say,
tunes nothing.
