[NLRS] Checking out performance of a satellite ground station

[Jon Platt]

That some of the coax connectors were not weather sealed may not be good.  I have seen cases where there has been water in the feedline but that the SWR was still low, so SWR alone may not be an indicator.   My only thought would be to borrow a Time Domain Reflectometer (TDR) that can see any bump in impedance along the feedline.  I do not own a TDR but perhaps someone on the list here may.  Otherwise a visual inspection by moving the connector and seeing if moisture is present can work too.   Good luck.
