An antenna does not have to be tuned exactly for receive only, I don't know where this myth came from. and an antenna only has to be tuned close to transmit, I can just imagine someone having antennas tuned for every frequency in the two meter band, a 4Mhz band.
I have my 2 meter transmit/receive antennas tuned for 146.000 the center of the band, they work well of 144 and 147, the highest swr is less than 2:1.
Let the flames come, but be prepared to back up your replies with factual data, links to websites perhaps.
