[Antennas] Antenna SWR

Didn't say how much of a change. Could just be the wet ground under the antenna. Lower ground losses would probably push your swr up.

Subject: [Antennas] Antenna SWR
I just got a new play toy, an antenna analyzer, and have taken some SWR 
measurements on my antenna. I have a Butternut HF6V. This morning I 
measured the SWR. Shortly afterward we had a rain storm. Out of 
curiosity I measured the SWR again and found a significant upward change 
on all bands. I am confident there is no water egress at the connection 
of the feed line to 20M 1/4 wave transformer section. All joints on the 
antenna were assembled with Noalox. Maybe there could have been some 
water egress at the connecting lugs of the the 1/4 section on the 
antenna where they connect to the antenna but they appear to be sealed.
Should I expect a SWR change just from a wet antenna?
