I've had my mobile setup for several years. A Galaxy 979-DX, driving a 2-pill amp, with a 102" stainless whip mounted on the passenger's side rear sidewall of the bed of the pickup. I'm using "standard" off the shelf thin coax (18'). This is all setup in a 2007 Toyota Tacoma.
Over the last several weeks, I've attempted to replace the 2-pill amp with (3) different 4-pill amps and continue to get the same problem, which is intermittent activation of the ABS light, which turns-off the anti-lock brakes. I've never had this problem while using several different brands of 2-pill amps. I've tried a 4-pill RM Italy amp, a 4-pill Palomar and now a 4-pill Texas Star. They all will intermittently turn the ABS light on.
In each case, I've had the amp grounded to the frame. I even ran another ground from the shielded side of the coax (at the antenna mount) to the wheel well. I still have the problem.
Some of the locals have speculated that I may have stray RF through the coax which may be activating the sensor. I have off-the-shelf type thin coax, meaning nothing top-end or high-quality. My question is, do you think it could be coax related? If I upgraded to a better coax, would I have a good chance of fixing the problem? If I were to upgrade, what do you suggest? I'd like the coax to stay as thin and pliable as possible an still be able to correct the problem. Power wise, the amp is dead-keying about 120-watts and swinging to 475 or so.
