actually i saw plenty of complaints from russian side that when they start jamming they can't operate their own equipment (drones, radio)
on same topic, recently one of Ukrainians blogs write that they started to make suicide drones with SDR that tries to lock on jamming source and blow it up
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/
