Also good idea when considering lightning protection issues.... Rob K

The additional advantage is to give you diversity and some immunity against multipath (at least it reduces the probability that both receivers will be affected at the same time due to weird constellation issues or local interference). But it now creates an issue which is how do you know who is right when both receivers don't agree...

Yes, I've seen this. On installations in the past, when we were putting up dual GPS systems, we always put them at least 10 metres apart. What is actually best practice, is to put one at one end of building and the other one at the other end.

When doing mobile GPS receiver testing at work with a single antenna feeding multiple receivers through a splitter, we sometimes had to insert attenuators in each receiver's antenna feed to keep them from jamming each other. -- Mark J.
