The X-2 antenna is a unique weapon in the Fallout: New Vegas add-on Old World Blues.


It is one of the many special antennas used to make the radar-guided repulsive field around the Big Mountain Research and Development Center, and for the transmissions of the X-2 array. When used as a weapon it focuses brainwave patterns and does electrical damage, causing extra damage to robots and power armor users.

Special attack

It has a special Pain Frequency attack that does 200% damage in V.A.T.S. at the cost of 13 more action points (requires a Melee skill of 50).

Note: Melee weapons do double normal damage in V.A.T.S.

It is possible to execute Pain Frequency outside of V.A.T.S. (without the required Melee skill of 50 to perform the move) by initiating a power attack (hold attack button) while moving forward.


The X-2 antenna can successfully strike about 620 times from full condition before breaking.



  • It is needed for the quest X-2: Strange Transmissions!, but is not a quest item and can be dropped right after obtaining it, as the blue print is already transferred to Dr. Klein.
  • If your Strength level does not meet the recommended level for this weapon (7), then the attack speed of the antenna is painfully slow, and could possibly make it the slowest weapon in the game, regardless of the fact that the super sledge is 5 lbs heavier than it and attacks faster.
  • As an EMP melee weapon, it is relatively powerful against machines like robo-scorpions, which it often knocks back with each hit.
