No it doesn't need to be matched to the line!
They often aren't.

Well, doesn't have to be, but if you are using coax , it should be to
reduce feedline losses. Would be a concern the higher in freq you go.
I'd never run a severe mismatch on VHF or higher unless the line was a
low loss ladder line. But I rarely use ladder line on VHF... I do run
mismatches on HF at times, usually on the warc bands using my 80/40/20
parallel dipoles fed with the tuner, but I am taking a hit with some
feedline loss. Good ladder line is low enough loss, even with a large
mismatch, you don't really have to be matched. 85% of the antennas I
use are coax fed, so it's more important to me than it might be to
others using ladder lines. MK
