To complete the Radio Tower portion of the Triangulation order in Modern Warfare 4 DMZ, activate the order, use the orange objective markers to find two eligible Radio Towers, climb each one to its highest platform, and hold the Place Radio Transmitter prompt on the mast or support beam. You do not carry a transmitter as an inventory item. After the two tower placements, finish the order at the rooftop antenna at La Grande Vie in Songdo Wharf.
The objective is easy to miss because UAV Towers are separate structures, the interaction is usually at the summit rather than the base, and tower layouts can require mantling or short jumps.

Triangulation is an order in the Underground chapter. Its sequence is:
- Place a transmitter on one marked Radio Tower.
- Place a transmitter on a second marked Radio Tower.
- Place the final transmitter at La Grande Vie in Songdo Wharf.
The first two objectives are tracked as a two-tower counter. Check the counter after every interaction so you know whether the game accepted the placement.

How do I place the transmitter on the first Radio Tower?
- Activate Triangulation. Open the Tac Map and identify the orange Order Objective markers. Only towers marked for the active order count.
- Choose a marked tower. Confirm that the structure is a tall, climbable Radio Tower, not a UAV Tower or another communications structure.
- Reach the summit. Climb the ladders and platforms. Depending on the layout, you may need to mantle ledges or make short jumps between tower sections.
- Find the interaction point. At the highest platform, face the mast’s metal support pole or beam. Move your aim along the structure until Place Radio Transmitter appears.
- Hold the interact button. Do not just tap it if your control layout requires a hold. The objective counter should change to 1/2.
The prompt may appear only when you are standing on the correct upper platform and looking at the structural beam from the right angle. Search the mast itself rather than the ladder, railing, or nearby roof.
How do I complete the second tower placement?
Travel to another orange-marked Radio Tower and repeat the same climb and interaction. When the game accepts it, the tower counter reaches 2/2. The order does not require a particular universally fixed pair: when several eligible markers are present, select the two that are practical for your deployment.

| Selection factor | What to check before committing |
|---|---|
| Travel distance | Pick a marked tower that does not force an unnecessary cross-map run. |
| Climb complexity | Prefer a route with continuous ladders and broad platforms if another marked tower has awkward gaps. |
| Enemy exposure | Scan for nearby AI and other operators before beginning the climb; the upper platform leaves you visible. |
| Descent safety | Leave enough time and cover to climb down safely instead of jumping from the summit. |
There is no single shortest or safest tower route that applies to every deployment. Orange markers and the counter are more reliable than memorizing a fixed pair of locations.
Where is the final transmitter at La Grande Vie?
After the tower counter shows 2/2, go to La Grande Vie in Songdo Wharf. Enter the building, use its interior stairs or another route to reach the roof or top area, and interact with the rooftop antenna or mast. This is the third placement in Triangulation, not an optional extra step.

- Hold interact and verify that the order completes or advances.
Do I need to carry a transmitter?
No. Triangulation creates the transmitter through the interaction at each objective location. Your backpack does not need a transmitter item, and finding or looting a separate device will not replace the tower interaction.
Why is the transmitter prompt not appearing?
- You are at the wrong structure: UAV Towers do not satisfy Triangulation. Return to the Tac Map and follow an orange Order Objective marker.
- You are too low: Continue to the highest platform. The prompt is placed on the upper mast or support beam, not normally at the ladder base.
- Your aim is off the beam: Stand close to the summit structure and slowly sweep your reticle across the metal pole or beam until the exact prompt appears.
- The order is not active: Confirm that Triangulation is selected before traveling. Without an active order, the objective markers and interaction may not be available.
- The counter did not change: Hold the interaction until it completes, then check for 1/2 or 2/2 before leaving. If it remains unchanged, return to the marked tower and try the summit interaction again.
- The route is unsafe: Clear nearby AI, watch for other operators, and avoid rushing the descent. Falling or being eliminated can cost the progress you just made.
What should I know about tower locations?
Active tower locations can vary by deployment, and different guides may highlight different nearby towers. Treat the orange markers shown while Triangulation is active as the authoritative list for that match. A tower that was convenient in one deployment may not be marked or may be less practical in another.

Because the summit and ladder sections expose you, approach from cover when possible, clear enemies before climbing, and pause on a platform to check for other operators. Keep the Tac Map available so you can plan the second tower and the later trip to Songdo Wharf without confusing a UAV Tower for a valid objective.

Frequently Asked Questions
Can I use any two Radio Towers for Triangulation?
Use two towers that are marked as Order Objectives during your deployment. The available markers and the easiest route can vary, so the active Tac Map matters more than a fixed location list.

How can I tell a Radio Tower from a UAV Tower?
A Radio Tower is the tall climbable structure marked by Triangulation’s orange objective icon. A UAV Tower is a different communications object whose normal interaction does not advance the Triangulation counter.
What happens if I leave after only one tower?
The order remains incomplete until the second tower is accepted and the 2/2 counter appears. You can continue the sequence by returning to the remaining marked tower, subject to the normal conditions of that deployment.
Is La Grande Vie part of the same transmitter objective?
Yes. It is the named third placement after both Radio Towers, located in Songdo Wharf. The interaction is on the building’s rooftop antenna or mast.
