Try removing it. I've used mine with 4 different cars at the Las Vegas Silver Bowl where it's probably 250' from the drivers stand to the farthest point; never had a glitch. Never used the Futaba ant. with the Spectrum.
Since your broadcasting on 2.4 GHz through the transmitter module, the original ant. is inactive. It might cause some interference though??
Anyway, it takes 15 seconds to unscrew it and try.
Make sure your ant. has 1/2 inch of wire extending out of the ant. shroud.
