Quick Answer
Place a transmitter on top of each of 2 radio towers, then place the final transmitter atop La Grande Vie in Songdo Wharf. On each tower's highest platform, search around the four posts until you get the place transmitter prompt. Triangulation is Order 3 on the Underground chapter's first page, Part 1 of 2.
Which MW4 DMZ radio towers count for Triangulation?
Any two radio towers count, so mark a nearby tower rather than crossing the map for a particular pair. Use your tac map to find them; a distant marker can look like an orange balloon before changing into a tower icon as you approach.
Head for the radio tower your order marks on the tacmap.

Your goal is the highest platform, and the climb varies between towers. Some need jumps and mantles around the structure; others have a straightforward ladder climb. Both types work.
Avoid hammering jump during the climb. One player repeatedly jumped off an edge by pressing it again, and found that approaching a handhold from the side worked better than leaping straight at it. Look around for a gap in the fence before attempting another awkward jump.
Where do you place the MW4 DMZ transmitter on each tower?
Place it at the interaction point around the four posts on the highest platform. Reaching the upper level is only the climb; you still need to find and activate place transmitter.
Search the first tower's top platform
Climb all the way up, then move around the posts until the placement prompt appears. Interact there to place your first transmitter.
Climb the ladder all the way to the highest platform.

Use a descent zipline where one is available. Some towers have a button-operated descent, but others lack that route. A parachute gives you another way down if you have one.
Repeat the placement on the second tower
Climb the second tower to its highest platform and interact with the transmitter placement point again. This finishes the radio tower portion of the order.
A vehicle gets you to the second tower much faster.
Shown at 00:38 in Kasum Adventurer’s video.Where does the final Triangulation transmitter go?
The final transmitter goes on top of La Grande Vie in Songdo Wharf, on the map's eastern side. Head to the large building rather than looking for another standalone radio tower.
La Grande Vie is the highlighted building in Songdo Wharf.

Clear the enemies guarding your route. Player routes recorded October 21, 2026 differ: one uses an elevator before continuing to the stairs, while another takes the stairs all the way up after failing to find an elevator. If you cannot find the lift, keep climbing the stairs toward the roof.
The elevator inside La Grande Vie takes you most of the way up.

Once on the rooftop, climb up and jump across the ledge to reach the final placement point above it. Arriving on the main roof is not the last step.
Interact at the top
Place the last transmitter at the rooftop interaction point to complete Triangulation.
You do not need to activate the rooftop generator, use the security cameras or summon enemies for this placement. Colossus is not a Triangulation objective either. One player was killed after mistaking a Colossus summoned by another player for part of the order. If a commander is active nearby, check the MW4 DMZ bosses before committing to that fight.
What do you get after completing Triangulation?
Completing the final placement clears Triangulation and contributes to the Underground Part 1 of 2 page rewards. Those rewards belong to the whole page, which also includes Eye in the Sky and Watch for Bumps.
The reward names have two readings dated October 21, 2026:
| Reward reading | Page rewards |
|---|---|
| October 21, 2026 listing | DDOS, Decoy Grenade, Night Vision Goggle recipes; 20,000 DMZ Cash |
| October 21, 2026 player report | DOS, snapshot grenade, night vision recipes; 20,000 cash |
Finish any remaining orders on that page, then continue with Underground Part 2. The MW4 DMZ missions page is your next stop for the surrounding story missions and orders.
