I made a PCB with a RF95 and a Atmega328p. It is extremely disappointing in terms of range and reliability. Here is the top and bottom layers of that PCB.

I know I made a mistake in the trace of the antenna, but even after I modded it so that the antenna is directly solder on the ANT pin as shown in the picture below, I am getting a 50% uplink rate at only 125 meters (in an urban area, more or less line of sight).
Is there anything obvious I am missing? It’s been giving me a lot of headaches.
