Just modded my ST16 by moving the internal 2.4 whip antenna to the outside with a RP-SMA / IPEX cable. I am now using the Moxon antenna for telemetry (2.4), and FPVLR antennas for control (2.4) and fpv (5.8). I was losing telemetry data in and out at very short ranges. Now with this setup I loose telemetry and fpv at around the same distances/circumstances. Very happy. My H is still stock with the short whip antennas. Maybe for the Spring I will mod to allow removable sma antennas to give an even better reception link.
