There is an older term that I haven't come across in radio lately when referring to the relationship between TX and RX when it comes to tuning an antenna.  That term is reciprocity.  It states that anything that affects TX or RX will effect the other equally and in the same way.


This is limited to the antenna system.  This does not apply to the radio itself, which often has various circuits these days that filter/amplify the RX signal in various ways.
