Narrative:
Aircraft X landed on [runway] 6R during our over ocean procedures. He rolled to the end and exited at victor turning right on to echo. As he was exited 6R at victor; aircraft Y who was on a 2.5 mile final advised that the ILS just went all over the place and wondered what was going on. I advised him that the proceeding arrival was the super and that it was possible that the size of the super disrupted the signal. Aircraft Y then stated that it was showing normal again.the only thing I could recommend regarding aircraft X and landing on 6R; or 6L is that the subsequent arrival trailing the super should be no closer than 10 miles in trail due to the signal disruption. This would allow the super to safely exit the runway and cross the inboard runway if he lands on the outboard. That way the super would not disrupt the trailing aircraft while it's within a 3 mile final.

Title: An LAX Local Controller reports of a Super aircraft landing and then traffic following reports the ILS signal as being interrupted. The Super was exiting the runway ahead when the disturbance was reported.
