IMPORTANT
DO NOT SKIP THESE STEPS
THE TOWER MOUNTED AMPLIFIER MAY BE PARTIALLY DISASSEMBLED FOR SHIPMENT TO PROTECT AGAINST
BREAKAGE AND SOME ASSEMBLY MAY BE REQUIRED BEFORE USE. DO NOT CONNECT OR ATTEMPT TO USE THE
TOWER MOUNTED AMPLIFIER (TMA2Q) OR LNA POWER COUPLER (LPC2Q) BEFORE COMPLETING THE STEPS
LISTED BELOW. ALWAYS USE ANTI-STATIC PROTECTION WHEN WORKING ON THESE ASSEMBLIES.
1.
LOCATE THE DOCUMENTS FOLDER ON THE CD. OPEN AND PRINT THE TMA2Q/LPC2Q MANUAL. REFER TO THIS MANUAL WHILE
FOLLOWING THE STEPS BELOW.
2.
LOOSEN THE FOUR CAPTIVE SCREWS, ONE IN EACH CORNER OF THE TMA2Q ENCLOSURE COVER AND REMOVE THE COVER.
3.
THE ENCLOSURE MAY CONTAIN A BUNDLE OF BUBBLE WRAP. THE BUNDLE HOLDS ONE OR TWO LOW NOISE AMPLIFIER
MODULES DEPENDING ON THE TMA CONFIGURATION. THE MODULES ARE CONNECTED BY CABLES TO OTHER COMPONENTS.
DO NOT PULL ON THE CABLES. IF NO BUNDLE EXISTS, SKIP TO STEP 9.
4.
CAREFULLY EXAMINE THE BUNDLE AND CABLES COMING OUT OF IT. THERE IS A SIGNAL CABLE AND A POWER CABLE FOR EACH
AMPLIFIER. THE SIGNAL CABLES CONNECT THE LNA MODULES TO ASSOCIATED COMPONENTS. THE POWER CABLES CONNECT
THE LNA MODULES TO A CONNECTOR THAT WILL PLUGGED INTO THE POWER SUPPLY IN A LATER STEP.
5.
CAREFULLY CUT THE RUBBER BAND OR WRAP-TIE ON THE BUBBLE WRAP AND CAREFULLY REMOVE THE BUBBLE WRAP FROM
THE MODULE OR MODULES. DO NOT PLACE ANY TENSION ON THE CONNECTING CABLES AND DO NOT TWIST, SHARPLY BEND
OR KINK THE CABLES.
6.
LOCATE THE LNA MODULE WITH THE “CW” CIRCUIT TAG AND CAREFULLY CONNECT IT TO THE RF ADAPTER ON THE “CW”
LIGHTNING ARRESTOR. HOLD THE LNA MODULE SO THAT IT CANNOT ROTATE WHILE CAREFULLY TIGHTENING THE SMA RF
CONNECTOR. FIRST MAKE UP THE CONNECTOR FINGER-TIGHT AND THEN TIGHTEN WITH A 5/16 in (8 mm) TORQUE WRENCH
TO 3~5 in-lb (0.34~0.57 N-m). DO NOT OVERTIGHTEN THE SMA CONNECTORS!
7.
LOCATE THE LNA MODULE WITH THE “CCW” CIRCUIT TAG AND CAREFULLY CONNECT IT TO THE RF ADAPTER ON THE “CCW”
LIGHTNING ARRESTOR. HOLD THE LNA MODULE SO THAT IT CANNOT ROTATE WHILE CAREFULLY TIGHTENING THE
CONNECTOR. FIRST MAKE IT FINGER-TIGHT AND THEN TIGHTEN WITH A 5/16 in (8 mm) TORQUE WRENCH TO 3~5 in-lb
(0.34~0.57 N-m). DO NOT OVERTIGHTEN THE SMA CONNECTORS!
8.
PLUG THE POWER CABLE ON EACH LNA MODULES INTO THE CORRESPONDING POWER SUPPLY Vout CONNECTOR. THE CABLES
ARE COLOR CODED. THE RED CABLE GOES TO THE UPPER POWER SUPPLY AND THE GREEN CONNECTOR GOES TO THE LOWER
POWER SUPPLY. THE Vout CONNECTOR IS CLOSEST TO THE MIDDLE OF THE METAL CHASSIS PLATE AND THE SCREWS ON THE
TERMINALS POINT TO THE TOP OF THE ENCLOSURE. DO NOT FORCE THE CONNECTOR; IT FITS EASILY IN ONLY ONE
ORIENTATION. REFER TO THE DRAWINGS IF NECESSARY.
9.
CHECK ALL CONNECTIONS IN THE ENLCOSURE FOR SECURITY. DO NOT RE-TORQUE CONNECTIONS THAT ARE TIGHT.
10. CHECK THE RUBBER GASKET IN THE ENCLOSURE COVER FOR PROPER PLACEMENT AND SECURITY. REPLACE THE COVER ON THE
ENCLOSURE. TIGHTEN THE FOUR SCREWS IN AN ALTERNATING PATTERN SO THEY ALL ARE SNUG. DO NOT OVER-TIGHTEN.
