Default MW Link passing thru high voltage wires

Is there any effect in MW link's RSL when it passes thru a high voltage wires?
If there is, how much?

HT wires doesn't affect MW transmission since the frequency of high voltage lines is 50-60Hz.

Default Power lines crossing the path

I think the impact is negligible for normal high voltage power line crossings in the far field (fraunhofer) region, even for power lines inside the (first) fresnel zone. Power line pylons/towers should be treated as obstructions.

Power line crossings in the near field of an antenna should be avoided because of possible disturbance to the radiation pattern and cross-polarisation degradation.
