Actually that is confirmed to be true. I can get the TX unit to be properly received without any sort of TX antenna, not even a wire, up to 15 meters away (with a house in between).
I can the signal at least (did not test further away) 25 meters away just by placing (without any solder) a piece of ~17cm AWG22 wire over the TX module antenna hole.
So in practice an antenna on the TX side is optional. At least for me.
