When you see a low SWR at say 7.8 MHz, this is an indication that one of the
coils has opened (corrosion, broken trap, etc). But if the SWR is flat across
the band but higher than previous, I would agree with K7LXC and the process to
resolve. Regards,

Methinks you have a feedline problem. I'd start at the antenna
checking the swr and work your way back to the shack from there.
A feedline failure usually indicates higher swr but if there's no dip
anywhere (did you check above and below 40M?), then it doesn't look like an
antenna.
