why do you guys keep doing range mods that dont work?
why do you guys think that adding a different color antenna makes your car "custom"
cat-5, copper wire crip caps all of that does nothing or very little to increase your range.
if you want to double or triple your range do these two things:
ad a third battery to the controller. this is the most effective mod but it requires a little soldering and circuit knowledge.
the other and most easiest one to do is ad a bigger antenna to the controller. this also requires soldering but it is a lot easier to do than any of the other mods.
all cat-5 wire does is let you choose your color. it does not increase range unless you want an antenna sticking 3foot out of the car.
removing circuitry from a little circuit board is a dumb idea. how many of you wrecked a board from doing that???
if range is a concern start with the simplest and least intrusive fix first. you can buy telescopic antennas from radioshack for 3-5bucks or take it off of an old cordless phone base.
