Sap, that's never been the case. Since the earliest days of the technology the term "aerial" was used for both transmitting and receiving installations. Check out some of the very early Marconi literature. And, actually, it was Marconi who later brought the term "antenna" into common use.
One of the fundamental tenets of antenna engineering is reciprocity: an antenna can be used interchangeably between transmitting and receiving. In practice, passive or active means are sometimes used to restrict operation to one or other application. But the antenna itself is completely reciprocal.
The US IEEE style of "antenna" and "antennas" is universal in professional international use and, indeed, the British IET journal (which is also widely read internationally) is called "IET Microwaves, Antennas and Propagation".
Popular usage does vary a bit, with older folks in the UK, Australia and a few other places still using "aerial" - most often for the wire style of HF antenna in my observation.
On the substantive question by the OP: go for 2 antennas!
