GTA Online signal jammers represent a different type of collectible hidden around the world of Los Santos and beyond, as you don't actually 'collect' them in the traditional sense by picking them up. Instead you have to destroy each of the 50 jammers by shooting them, once you've spotted the flashing boxes high up on buildings and other structures across GTA Online. There's the usual offering of cash and RP for taking them out, though the final goal is to unlock Avi Schwartzman as a hacker for your Diamond Casino Heist crew, who can really help increase your take from that particular score. To access him you need to disable all 50 of the tiny transmitters, so here's how you go about finding and destroying all of the GTA Online signal jammers.
How to find GTA Online signal jammers
The GTA Online signal jammers locations are often high up on billboards or the sides of buildings, so once you're in the right area you'll normally need to look up to see them. Bringing a sniper rifle with you, or piloting a flying vehicle with attached weapons, should help with damaging the unit enough to put it out of action. With your gear prepared, use the below map to help you pinpoint the exact location of each jammer.
GTA Online Signal Jammers locations
On the map above we've marked all 50 of the GTA Online signal jammers locations, and for a closer look you should click on the image to expand it to full size. Bear in mind the advice we gave earlier, so if you arrive in one of the areas and can't see or hear the signal jammer then it's probably attached to a structure high up above you, so mark sure you scan the area throughly and if necessary come back in the dark to see if you can see that twinkling light.
Once you've disabled all of the GTA Online signal jammers, you'll unlock the hacker Avi Schwartzman to join the support crew for your Diamond Casino Heist team. They're a great asset to have on board, as their hacking skills can help you overcome security systems and maintain your cover as you attempt to pull off your huge robbery at the casino. Stock up on ammo, pick your favourite vehicle, and get hunting those signal jammer units.
