Why not try the same tactic, fly low. When they fly low sometimes they also lost their DL, so its not without disadvantage. From there you basically playing hide and seek.
Another alternatif is fly very high and set your radar elev to low. Drag them in the open terrain and try not to play by their rule.
Another risky tactic is to turn off your radar until they come inside 30 miles (with the help of DL or AWACS when available). Well.... why you wanna do that? Let me tell you that almost every pilot try to notch/beam/fly low NOE when their RWR nails incoming F-14 fear of its Phoenix. By turning off your radar you encourage them to come closer on medium alt after that start lob them your Phoenix.
Good luck
