Default effect of close property fence on dipole arrays and solution?

I put up a 20 meter dipole array a while back and I don't seem to be

surrounding the property. *I'd say the southern leg of the array is about
25' away from the fence. *So I ask the question: what effect can fences have
on antennas and what are some possible solutions? *I can rule out moving the
antenna because I lack the room to move it any further away from the fence.

Thanks,

AT 20 ft above ground the antenna may be performing more like an NVIS
antenna radiating most of the signal upwards. Unfortunately 20M is not
a great NVIS band.
