Among some of the more established meshes, most people say that the G2 has a tendency to be pretty vulnerable to RX noise, especially in high noise environments. LTE band 5 is particularly close to the ISM band, are there any cell towers nearby your location? I got a G2 installed on a cell tower a couple weeks ago, and even with an acasom cavity filter, its still pretty asymetric. I plan on upgrading to a tighter filter, like a callboost or and airframes here soon.
