What Are Signal Jammers?
Signal Jammers are one of GTA Online's collectible hunts, added with The Diamond Casino Heist update. There are 50 of them hidden across Los Santos and Blaine County — small black electronic boxes bolted to walls, poles, billboards and rooftops.
Each jammer gives off a faint beeping sound and a tiny blinking red light, which is how you spot one when you're nearby. They're completely harmless — they won't fight back — but tracking down all 50 takes patience and a sharp eye.
Locations Map
Where to Find Them
The jammers are spread map-wide but cluster heavily inside the city. Work through one region at a time rather than driving back and forth:
Downtown & Pillbox Hill
The densest cluster. Check skyscraper walls, multi-storey car parks and rooftops around the financial district.
Vinewood & the Hills
Billboards along Vinewood Boulevard, plus jammers fixed to hillside mansions and studio buildings.
Rockford Hills & West LS
Upscale storefronts, the Galleria area and walls around the tennis club and golf course.
Del Perro & Vespucci
The pier, the promenade and apartment blocks along the western beachfront.
East LS & Mirror Park
Industrial walls, low-rise rooftops and utility poles through the eastern neighbourhoods.
South Los Santos
Strawberry, Davis and Chamberlain Hills — fences, shop walls and freeway overpasses.
LS Harbour & Docks
Shipping containers, cranes and warehouse walls around the port and Elysian Island.
Blaine County
Far fewer out here — scan Sandy Shores, the Grapeseed farms and structures around Paleto Bay.
Don't do this from memory. Keep the map above open on a second screen and tick each jammer off as you go — they're small and very easy to drive straight past.
How to Destroy a Signal Jammer
You don't need to touch a jammer — you just need to damage it. One hit is enough, and you can do it from a distance with line of sight:
Shoot it
A single bullet from any gun destroys it. A scoped or sniper rifle handles jammers high on walls and billboards.
Use explosives
A grenade, sticky bomb or rocket will take out a jammer instantly — handy for clusters.
Vehicle weapons
An armed helicopter or weaponised vehicle makes quick work of rooftop and high-rise jammers.
Know when it's done
A destroyed jammer stops beeping and its light goes out — your confirmation it counted.
Collecting Tips
- Hunt at night — the blinking red light is far easier to spot in the dark.
- Turn the in-game radio off so you can actually hear the beeping.
- Most jammers sit above head height — get in the habit of looking up at walls and billboards.
- A helicopter makes reaching rooftop and high-rise jammers painless.
- Do the hunt in an invite-only session so nobody interrupts you.
