Hi I got one of these transmitters just to try 2.4 out
I've wired it all up correctly bonded it all as we'll however I'm only getting about ten meters of range until it cuts off I've got a total of six receivers in different cars and there all the same I've even used a aerial tube to extend the length of the Aries ( so it still sticks out the body shell) any help is most welcome thanks
