Hi! I had Predator V2 kit with the 250mw original tx and skew antennas Range was maximum 500-700meters flying high and 200meters in lower heights. I like to fly low and needed better transmitter so I bought Immersion 600mw. Didnt change antenna or anything else. Only disconnected old tx and put in new tx. I could immediatly notice worse color quality and with a quick test I had bad reception at 10meters away and after 50meters only noise. What could this be? Bad tx or do I need to upgrade rx in the goggles?
