When GPS first started to be fitted to light aircraft it was found that LO leakage from some VHF navigation recivers blocked the GPS when the NAV was on certain channels. You can buy a BNC "T" adaptor where the leg of the T is a 1.5GHz coax stub notch filter. They go on the NAV RX antenna connector. Robert G8RPI.

Every amplifier has reverse parameters, so a small amount of the crud (circuitry noise) from one GPS will reach the other GPS. Not much, but some people are nuts about time. This is a bigger problem with radios, where the locals from one radio can reach the input to the other radio. I was also confused on the notion of a transmission line splitter. Is this a Wilkinson or something else? On 10/9/2012 12:40 AM, Azelio Boriani wrote: > Crosstalk?
