Running down 2 lane highways... I get good signal on all 3 axles... on Interstate or other times where cars are on the side of me for a long time, I tend to lose signal.
Geez.. it's only a 34'!!!
Ok, so, I get a 'repeater'... I mounted it near my rear bumper of the TV.. tied it into the 'running lights' of the TV.. So, all I do is turn on the headlights when towing (something I always tended to do anyway)... and the 'repeater' only runs some times..
Peace and Blessings..
