I recently fitted a choke-balun to the feedpoint of my temporary [and rather poorly-elevated] 28MHz half-wave dipole; it didn't seem to reduce the noise-level but clearly did 'something' to reduce imbalance as the SWR dropped from 1.5:1 to 1.2:1

[I really must do something about getting a proper 28MHz antenna setup]
