Topband: Bev flex high noise troubleshooting

[WW3S]

I noticed during the arrl contest my ewe configured bev flex seemed to have a higher than normal noise level. It’s gotten worse. I checked and rechecked all connections, and reterminated them. Still high noise. I assume my next step would be to check all the coax feed lines, what would be the best way to do that? Also open to any other troubleshooting tips
