LABRADOR
Installation Instructions
Parsec’s Labrador is a compact two-in one MIMO LTE external
antenna. This unobtrusive omnidirectional antenna works on
all the common North American LTE bands with high efciency.
The Labrador is optimized for attachment to a sheetrock wall in
an ofce environment. It is ideally suited to indoor applications
where a higher performance alternative to screw on antennas is
required. The Labrador has an IP65 ingress protection rating and
may also be mounted outdoors.

CHOOSING THE BEST METHOD AND LOCATION FOR INSTALLATION
CAUTION:
To get the best signal, your antenna must be mounted in an isolated area. It is important
to stay away from any interference including existing antennas, cluttered areas, or other
situations that might interupt network.
Make sure the antenna is at least 2 feet away from other antennas. Other Antennas
typically need to be 5 feet away. Antennas MUST be away from Outlets, AC or
Heating units, or anything with an electrical motor. All of these items can cause
radio interference and reduce antenna performance.

REQUIRED TOOLS
Hammer / Rubber Mallet
Phillips Screwdriver
Drill
Assemble the mounting bracket on the antenna using the four plastic thread forming screws. (Figure 1)

Step 2.
Step 2.
For best performance it’s important that the antenna be mounted at least 2 feet away from other
objects with a clear view of the horizon in as many directions as possible. Non-penetrating roof
mounts allow the antenna to be moved away from other objects and a mast height of about 6 ft.
puts the mounting hardware and RF connections near eye level during installation. Select a mounting
location away from air conditioning units and other large metal objects.
Mark the position of the screw holes on the wall to mount the antenna on the wall. (Figure 2)
Drill 0.2” holes on the wall and install the anchors on the wall. (Figure 3)
Select one of the mounting option below, depending on your use.
- Wall Mounting (Included)
Using the 2 anchors and included screws the antenna can be mounted on
a panel or a wall.
- Mast Mounting (Included)
Using the included clamp saddle, v clamp bolt, and nuts and washers you
can mount the Labrador on a pole for better isolation.

Step 3.
Align the mounting hole on the antenna to the wall mounting holes and fasten it to the wall using two
screws provided in the kit. (Figure 4)
Pole Mounting Instructions
Step 1.
Step 2.
The mast/pole should be a diameter of between 1 and 2.5” to mount the antenna. (Figure 5)
Mount the antenna on the pole leaving at least one inch of mast above the clamp. (Figure 6)

Step 5.
Tighten the 2 nuts with your ngers, making sure equal lengths of threads extend past the nuts.
Properly route the cables making sure there is no sharp bends. Clamp the cables to the wall at about 6
inches away from the antenna if the cables are being hung straight from the wall. (Figure 8)
Attach the two RF cables to the mast roughly 1ft. below the RF connectors to provide strain relief. Vinyl
electrical tape works well for this without risk of deforming the RF cables. Black UV resistant zip-ties can
also be used if used carefully, but tan Nylon zip-ties rapidly deteriorate when exposed to the sun.
Use a 7/16 in. wrench to tighten each nut one full turn beyond nger tight to compress the lock washers.
(Figure 7)
Make sure the antenna is mounted in the correct direction and tighten the mounting hardware.
Waterproof the RF connectors using electrical tape or a heat shrink tube.

Routing the Cables

Step 1.
Step 2.
Step 3.
Step 4.
Cables on the antenna are labeled as follows, LTE-1 & LTE-2
Clean the connectors such that there is no dust in the terminals.
Connect the cables from the antenna to the similar labeled cables of “Cable Kit” (Figure 9)
Carefully screw the N male connectors of the coaxial cable onto the N female connectors on the
antenna. If the connectors do not screw on easily using ngers, stop. The connector may be cross
threaded. Unscrew the connector and try again. Tighten the N connector rmly to compress the
water-tight gasket inside the connector and to keep the connector from working loose. Channellock
412 small V-Jaw pliers may be useful for getting a grip on the connector. The required torque is only 15
inch-pounds so be careful when using this or other tools to tighten the RF connectors.
Connect the cables from the antenna to the designated connector on the router using a SMA torque
wrench with a torque limit of 3 to 5 inch-pounds is recommended. If a torque wrench is not available,
it is possible to carefully tighten SMA connectors a 5/16 in. wrench if you use one nger no farther than
2 inches up the wrench to limit torque.

Cable Type: LMR200
Connectors : N-Type or SMA
Cable Labels: LTE-1 & LTE-2
Cable Kit: PC2402L40NFSM (REQUIRED - PURCHASED SEPRARATELY)
Mounting Hardware:
Check each coaxial cable connector and conrm it can’t be easily unscrewed with two ngers. Visually inspect
coaxial cable run for proper mechanical support.
Conrm the connection to a cellular network. Use a cellular device’s built in diagnostics to conrm RSSI better than
-75dB. Conrm the cellular connection supporting communication at required data rates. Carry out VSWR check,
should measure. Connect Cellular/ LTE & WLAN cables or stow unused pigtails.
