Nebo-M AESA complex consist from 3 radars, 1 VHF working in metric diapazone, 1 working in dm diapazone and 1 working in cm diapazone. Max range is 600 km. VHF radar see stealth planes without problem and having more Nebo-M complexes in different locations mean, that they could triangulate stealth planes very precisely for the use of air defense and fighter jets.
Older Nebo-SVU VHF radar, which was the first AESA VHF radar, have enough small cell for target location, that S-300 complex could launch missile on it without using of tracing radar. It was used only to guide missile to the cell of Nebo-SVU radar and there missile itself will find and attack the target. No need for tracking radar to actually see the target.
Modwern AESA VHF radars are precise enough for air defense use, specially when there is more of them in different locations and they triangulate targets. In that case stealth doesn't mean any advantage. SHORADs and medium range SAMs will use optical channels against stealth planes, so for them VHF radar is enough. Don't forget that Russian IADS also have a lot of different passive ELINT complexes, which could detect any emmiting from planes and stealth F-22 and F-35 also use radars, data links, TACAN, communications, IFF, etc, so they will be precisely tracked from long distances for the use of air defense.
