I am correcting you. Twisting wires causes cancellation of RF
energies. This is true for wires that have RF energy on them that
you wish to keep from emitting RF energy or wires that do not have RF
energy and you wish to prevent them from receiving RF energy.<br><br>
Therefore, if one could twist battery cables tightly enough, one might
reduce RF emitted from them. This is not always practical for 4/0
cables, but is practical for small gauge sensor wires.<br><br>
One of the best wires for rejecting RF energy is your garden variety Cat
5 cable. We use it to send audio signals (I volunteer as a
technician for entertainment events) for up to 2,000 feet and in the same
cable is a ring line with 100 VAC at 20 cycles. There is no cross
talk. What also makes this possible is the audio signals are a true
balanced signal -- every electron that moves one direction causes
another electron to move the other direction in the other cable.
This allows "common mode rejection." This is cancellation
of any induced signal. The induced signal causes electrons to move
in the same direction at the same time in both wires of the pair.
This equi-direction signal can be easily removed by a transformer or
matched linear amplifiers.<br><br>
I go into this detail only in hopes engineers with Outback might see if
these principals might be applied to future designs.<br><br>
