Default Antenna designs for noise cancellation on HF bands

Hi! Any one come across any designs for recieving antennas for HF
(especially 14 MHz) for use in a situation with a lot of QRN.
This seems to be radiated from local power lines, but despite the lnes in
our subdivision being underground we still get a S6/S7 noise level.
Yes we have contacted the authorities but so far no useful result.
It seems somewhat worse on my 5/8 wave vertical than on my G5RV doublet.
Neither myself no a neighbouring Ham have been able to find a way around
this problem despite us both being experienced "old timers".
Some sort of "noise antenna" and phasing arrangement is contemplated but
we have not as yet found a suitable design.
Any ideas welcome!

I have not tried it myself, but MFJ makes a noise cancelling doo-dad called
the MFJ 1026.
