I think you'll find the quoted statement below to be nonsense, Chuck, I 
think he made that up.  Hams in the 40's and 50's [and probably before] 
used one antenna because antennas are expensive and require space.  None 
of the ham community I knew when I was first licensed in pre-transceiver 
days [1953] used separate receiving antennas.  I remember being given a 
Dow-Key coax relay with a movable spring-loaded pin on the receive side 
that shorted the RX when in TX for the first TX I built from scratch [2 
807's in PP to cancel the 2nd harmonic of 10 m in Channel 2].

Transceivers came along near the end of the 50's and were undoubtedly a 
huge motivator for the shift from AM to SSB since you were guaranteed to 
transmit and receive on the same frequency, removing one of the 
difficulties of separate TX and RX, and zero-beating with no carrier.  
Separate RX antennas were the rule in maritime CW at the time, TX and RX 
sites were separated by miles.

Separate RX antennas sort of crept into the ham vernacular much later, 
mainly in the context of large contest/DX superstations. It is certainly 
true that while a Beverage RX antenna can produce a really desirable S/N 
ratio over the TX Inv-L on 160, and you would never want to TX on it, 
the reason most of us do not have Beverage RX antennas is we don't own 
enough land.  I believe that Don Wallace, W6AM, who definitely owned 
enough land had several Beverages scattered around under the multiple TX 
rhombics. [:-)
