Hi Gord,
I agree with all the suggestions done in the post above regarding antennas.
I just want to add something about the RF Efficiency. It isn't an instant measure like SNR, instead, it compares the number of data packets received during the last hour with the number of data packets sent by the receiver, and then computes the RF Efficiency. So, when one of the units is turned off or reset, the RF Efficiency value always start with low values, and start to increase until the first working hour. After that it should start to stabilize.
Another hints: Before buying any new antennas, specially on the TX, try something which was already suggested: Attach one single wire of around 17cm to the central pole of the SMA connector. From my experience, those small antennas aren't good for transmitting, while usually work well on the receivers.
