Probably true. But I very rarely have enough isolation between my antennas. So if I try diversity, the front end protection relays start buzzing when I transmit. The consensus seems to be that you shouldn't rely on the relays. The main antenna is simply disconnected while transmitting. Why isn't the sub-rx antenna? You're absolutely right, as long as I can't use diversity, dual watch would help me just as much as having a sub-rx does.
