Rf will be picked up by any wires.
As long as the rf voltage is not too high and/or it gets rectified by a diode, transistor etc it probably will not cause harm.
In this case you have a long wires going to your wind senders so odds are you will have lots of rf voltage.
Need to reduce the voltage.
If you want to test will need an rf probe or an oscilloscope that works at the ssb frequency.
The first thing I would try is to run the wires to the wind sender through a toroid close to the controller.
I'd do a least a couple turns.
Need a toroid rated for the ssb frequencies with a hole big enough. You can ignore power rating,
As an alternative could run each wire through a small toroid or "bead".
Still do a couple turns. do all wires even common and grounds.
If that doesn't do it put .oo1 uf capacitors from each wire to ground or common on the controller.
