Quick Erect Antenna Mast System (QEAM)

NSN 5985-01-381-6341, Model AB-1386/8

The QEAM is a mobile quick erect antenna mast used for elevating tactical communications antennas to a maximum height of 33 ft (10M) which results in more reliable communications over extended ranges. 

The QEAM replaces the OE-254, which is vastly more difficult to raise and lower due to its large volume of mast sections and other parts which are easily lost. 

The QEAM mast can mount antenna receivers (feed cones, etc) such as the AS-3166 (P/O OE-254), MP-68 (P/O RC-292), AS-4292 (P/O MSE) and A3005068 (P/O EPLRS).  The mast can be deployed and  operated in ground and vehicular (wheeled and tracked) mounted configurations.  The mast can be erected in 7 minutes with two persons and in 15 minutes with one person. 

A funded requisition for NSN 5985-01-381-6341 will provide the quick erect antenna mast with ground mounting accessories.  For vehicle mounting applications (the preferred mode), see below for appropriate NSN's.

For more information, check out the QEAM information page (PDF), or go to the Will-Burt website. has also rounded up some Preventive Maintenance and Safety information from PS magazine.
