That shouldn't pose any problems The down converted frequency from the LNB is between 950 - 2150Mhz. Even in the worst case if the shielding doesn't help, only the 18khz - 22khz DiSEqC signal alone is likely to get distorted, but since the diseqc bus is assumed to be a lossy bus -- there are several re-transmissions even in that case. So that also might not pose a threat, other than a sometimes a larger delay in switching from position: A - B., or in some cascade. If you are positioned to a satellite with a faint footprint, then better to have better cabling to avoid signal degradation causing the demodulator not to acquire a Lock. If the signal is pretty much strong, then this shouldn't be an issue. If you don't have a diseqc switch, none of these do matter. But another point to be noted is that some LNB's use the 22k tone to switch between polarizations as well, rather than the usual 13/18v control.
