Q. Is there a relationship between the efficiency of an antenna and the

received signal strength?

Signal to noise ratio, very little. Received signal level vs
a more efficient antenna, can be quite a bit. But if the s/n
is appx the same, no biggie.. Lower level on the S meter, but
things should sound about the same when listening to it.


You forgot the noise generated by the receiver. With a weaker signal,
the S/N ration will be lower.
