So I have switched to TBS Fusion as my daily driver for almost a month now... and did some lr missions too!
This was one where I went for 4km recently on an awful day for flying lr. The atmosphere was heavy with fog and clouds and was dripping from time to time(free air rf propagation attenuation was high)
I used a 13dbi patch and an Omni antenna on the latest FW.
