Hi, All I am trying to chase down a 2-3-4 ns/day "anomaly" in a gpsdo I am working on - it could be temperature sensitivity in the antenna (cheap patch jobbie), or I suspect my sealing of the outside connectors may not be watertight. I just wanted to ask the list of anyone know of/has an estimate of how much the propagation delay on an N and/or SMA can reasonably be expected to change in the presence of water? is 3 ns in the right ballpark, or would that effect be way bigger/smaller?
Likewise, does anyone have reasonably accurate figures for how much temperature could be expected to affect the delay of signals? 20 ps? 20 ns? Looking for some rough figures so I can look in the right direction.. I've used the same gpsdo, cable and location with a high quality antenna without seeing these effects, so I am fairly certain it is the antenna (or my reference maser giving up the ghost..) Thanks!
