I have used a Jumper T-Lite transmitter multi-protocol for 1.5years, and often fly drones with/without my friends. In general, I feel that transmission distance is shorter. For example;
- happymodel Mobula6 1s loses the signal around 15-25m without obstacles. FrSky binding.(but expect to reach around 150m) . max RSSI is 75, not 99, strange.
- BetaFPV micro drone 2s (forgot model) loses the signal around 50m.FrSky binding (but expect to reach around 400m)
- I have a free style FPV drones (iFlight and gepRC) with air-unit with FrSky XM+. They lose the signal around 1km. (but expect to reach around 2km)
- In general, I found city sides have radio interfere, and a huge parks without people kinda better, but not significant range improvement.
Does anyone know this is normal transmission range or too short and something wrong with my T-lite? I hope T-lite has booster option or may just change antenna simply, instead of installing additional kits.
