Default MA5B background noise

I've swapped the feed line over and its still the same.

When I put the antenna together I made sure all connections where good and
the analyser gave a good match on the frequencies I want to use.

I did use some conductive grease for the first time on the antenna. Wonder
if the grease is the problem or maybe this antenna just picks up a lot of
background hiss.

I have finally got my Cushcraft MA5B up in the air. But I am very
disappointed with it.

Is it normal for this antenna to have a lot of background noise behind
strong signals 9+?

The reason I ask is that I also own a cobwebb antenna and the side by side
comparison between them, there is no background hiss on the same strong
signals on the cobwebb S4 - 9+ but there is on the same signal on the MA5B
and it is enough to make listening on the MA5B very unpleasant even at
S9+.

Is this normal?

I will place my bet on a bad connector. How hard is it to swap
feedlines?
