Beautiful picture too with no pixelating. Normally in the afternoon/evening we only get the 38's reliably, the others randomly pixelate or indicate "no signal". Weird....
I agree with jrgagne99, your signals are marginal. Reception will vary according to atmospheric conditions, and rain will affect the trees in the signal path, making the signals weaker.

You could use 300 ohm twinlead, but you would still need to use a balun at the lower end.
If you can not measure it, you can not improve it.
