Exactly Rex. It gets interesting if he's cutting the cables for electrical
length instead of by physical length. If he's doing electrical length by
looking for a point where they're (n+1)/4 wavelengths long, he can just
change the frequency that he uses to find the null. I usually do mine by
electrical length. It takes out the slight differences.
