Hello Chris,
I am not aware of any issue with co-located/routed GPS antenna coax, but there are antenna spacing requirements (minimum 6 inches).
Not sure if this has anything to do with this problem, but do you have at least 6.5 ft of antenna cable between the 430W and the antenna? For RG-142B or RG-400 cable, this will ensure that the minimum required 1.5 dB of cable loss is provided by the cabling. This is required for a GA35 antenna.
For a group of antennas listed in the installation manual, the required loss is twice this amount. Additionally, as specified in the installation manual, to maintain integrity of the WAAS signal, the GPS antenna coaxial cable must have a minimum of two shields (e.g. RG-400 or RG-142B).
If you are using a GA35 antenna, would you please email me the serial number?
We would be happy to answer any questions you have about your installation if you provide the details.
Thanks,
Steve
