Good antiradiation munitions need a powerful warhead and a human in the loop.
making "dumb emitters" still require some engineering. also dumb emitters need to track patterns of proper jammers in order to attract proper attention: i am reading blog of somebody in reconnaissance unit of sorts. they been recording jammers working patterns. so i guess drones can be build to discriminate between targets
RPG munitions are not effective if the warhead is detonated too far away from the target, ie, because of a cage or net.
What you need is a real missile munition with heaving fusing and a casing.
i'll suggest to read it from the beginning to make a better sense of it https://ukrainevolunteer297689472.wordpress.com/
