Hi Gord,
think the best would be in your case if the antennas are parallel to each other.
Also, the transmitter module on your TX could also be of bad quality - sometimes the carrier frequency is drifting.
But I do not think that is the case because everything is good if you are close.
And in the end, the antenna could be of bad quality. Mostly you can say the smaller the antenna the result does not get better.
I use self made dipole antennas and I get an efficiency over 80% over about 50meters and one wall.
