EcoRenovator - View Single Post - How to monitor your PV production? A new idea?

I've been looking at the antennas in the receiver and transmitter.
They are little copper pigtails. Similar to the guts of a Rubber-ducky antenna.

I've been getting signal loss, maybe due to weak signal..

After seeing these photos, I see a problem. The receiver ant is vertical,
and the transmitter ant is horizontal.
At work, we call is Cross-Pol. Or Cross Polarization. Cross-Pol can cut
your signal up a theoretical 20dB. Which is a massive loss. (-3dB=50% loss).

I've rotated the transmitter 90degs. If that fails to get an improvement,
I'll install a better antenna on the transmitter.
