LXE Spire® Indoor/Outdoor Antenna
Introduction
The LXE Spire® Antenna is an Omni Directional Antenna for 2.4GHz Wireless LAN
systems. The Spire’s unique design provides improved pattern integrity over other omni
directional antennas currently available in the market place. This omni directional
antenna comes in both high and medium gain configurations and can be paired with a
number of accessories - Type 4 Rated weather proof enclosures, plenum rated ceiling
enclosures - to meet your specific installation requirements.
By combining LXE’s unmatched radio experience with EMS Technologies’ advanced
antenna designs, LXE offers an unparalleled 2.4 GHz wireless network solution.

Installation Instruction Sheet
Safety
The Spire bracket has been designed to attach to a wall, mast, I-beam or pole. To prevent
personal injury or equipment damage, the antenna must be securely mounted to each
plane per instructions.
WARNING
!
Antenna installations must be grounded according to local and national
codes. For your safety and others, do not install or work on antennas
near power lines. Install and repair all antennas or similar structures
out of falling distance of all such lines. Every electrical and telephone
wire is potentially dangerous.
CAUTION
!
This antenna is a low power microwave device. Always mount the
antenna at least seven inches away from personnel.
Location
The location of the antenna is important. Objects such as metal columns, walls, etc. will
reduce efficiency. Best performance is achieved when this antenna is mounted at 8’ to
40’ above floor level. If reception is poor, it's a good idea to try a few different mounting
positions to optimize reception.
Dual Spires
If using two antennas on one radio for space diversity, there needs to be 3’ to 8’ of
separation between the antennas.

Handling
Avoid dropping the antenna onto hard surfaces to prevent possible damage to the radome
and to the RF connectors.
Always hold the Spire Antenna cable near the RTNC connector when connecting it to the
bulkhead connector.
Mounting Of Spire With Bracket
This antenna is suitable for use indoors or outside. The antenna bracket attaches to a mast
(PVC pipe) from 1.5 " to 2.5" in diameter using the enclosed metal straps. When properly
mounted the Radome extends below the mounting bracket. In addition, the RF cable
attached to the antenna should have a dip in it that extends below the radome tip to
prevent water from running down the cable towards the radome.
The bracket can also be attached using U-bolts if desired. The bracket is designed to
mount to a vertical or horizontal mast. To install indoors, attach the mast to the truss and
have it extend at least 10” below the truss. Then attach the antenna to the bottom of the
mast. To secure to a roof, install a mast that extends at least 5’ above the roof and then
attach the antenna to the top of the mast with the Radome below the bracket.
To secure to a light pole, install a vertical mast above the pole or horizontal mast that
extends 3’ out from the pole. If the antenna is located below the top of the pole, then
attach the antenna to mast with the Radome below the bracket.

Mounting Of Spire Without Bracket
This antenna is suitable for use indoors only. It can be mounted to an acoustic ceiling
tile, a solid ceiling, or to an LXE Ceiling Enclosure. To mount to an acoustic ceiling tile,
use the mounting screws and nuts provided to hold the antenna to the tile. Make four
holes in the tile for the screws and one hole for the RF cable.
The Ceiling Enclosure comes with a kit containing screws for attaching the Spire to the
mounting plate in the Ceiling Enclosure.
The drawing below shows a typical setup with one antenna mounted to the center of the
enclosure.

Mounting Spire to I-Beam
The Spire Antenna may be mounted to an I-beam. The drawing below shows the I-Beam
clamp and screw configuration for the antenna mounting plate.
The screws must be tightened to a torque value of 40 in/lb (4.52 N/m).
