Antenna Installation
This section provides the information necessary for a professional antenna installer to install the
Extreme Networks antennas.
Warning
Antennas should only be installed by a qualified antenna installer. The antenna installation professional should be licensed or certified in accordance with local regulations.
Do not install the antenna in wet, windy, icy, or otherwise unsafe weather conditions.
Outdoor Antenna Kits
The ExtremeWireless outdoor antenna kits do NOT provide the following items, which may be necessary to install the antenna:
• Mast or other antenna support structure
• Guy wires
• All cables or other hardware necessary for a complete grounding system
• Waterproof tape
Note
It is the customer’s responsibility to ensure that an outdoor antenna installation complies with local radio regulations.
Installation Overview
Note
Not all antennas described in this chapter can be used by every wireless access point. Refer to
Antenna Models on page 13 to determine if your access point supports the specified antenna.
The installation process is summarized in the following steps. The following sections in this chapter provide additional details.
1 Make sure the APs are mounted and configured as specified.
2 Plan and implement a grounding system (if applicable) that meets local electrical codes and safety standards.

3 Install the lightning protector (if applicable).
4 Provide and install an antenna support structure as necessary. Make sure that the support structure is connected to the grounding system (if applicable).
5 Connect the exposed metal connectors of the low-loss antenna cable to the grounding system (if applicable).
6 Mount the antenna to the support structure.
7 Connect the antenna cables.
8 Route and connect the low-loss antenna cable to the lightning protector that has been installed indoors (if applicable).
9 Connect the cable assembly from the AP to the lightning protector (if applicable).
10 After verifying that the communications link is fully operational, secure all cables and use weatherproofing tape to seal all outdoor connectors.
Grounding System
Direct earth grounding of the antenna and the lightning protector is necessary to protect the installation from lightning and the build-up of static electricity.
Caution
The antenna mast, ExtremeWireless AP, and lightning protector must be connected to the same earth ground (with separate grounds), using an equipotential bonding conductor. A good electrical connection should be made to one or more ground rods using at least a
6AWG ground wire and non-corrosive hardware. The grounding system must comply with the
National Electrical Code and safety standards that apply in your country. Always check with a qualified electrician to determine whether your outdoor installation is properly grounded.
The grounding system must satisfy the following requirements:
• The antenna mast, ExtremeWireless AP, and lightning protector must be connected to the same earth ground using an equipotential bonding conductor.
• The antenna and the mounting structure require a separate earth ground connection. Check with a certified antenna installer to make sure the antenna is properly grounded.
• Ensure that the cable between the antenna and lightning protector is at least 0.9 meters (3 feet) away from high-voltage or high-current cable.
• A good electrical connection must be made to one or more ground rods, using at least a 10 AWG ground wire and noncorrosive hardware.
• The grounding system must comply with electrical codes and safety standards that apply in your locality.
• Have a qualified electrician verify that your outdoor installation is properly grounded.
Caution
A properly installed safety grounding system is necessary to protect your ExtremeWireless outdoor installation from lightning strikes and static electricity build-up.

Mounting the Antenna
This section includes requirements and mounting guidelines for the ExtremeWireless outdoor antennas.
Each antenna mounting section contains an illustration of the antenna, component description, and a mounting procedure.
Selecting a Mast
Note
You must supply your own mast on which to mount an ExtremeWireless antenna.
ExtremeWireless antennas do not come with masts.
To minimize the influence of obstacles, signal interference or reflections, install the antenna at least 2 meters (6 feet) away from all other antennas.
If you need to mount multiple antennas on a single mast, alternate the mounting of directional antennas for vertical and horizontal polarization.
In subfreezing conditions, the communications link could fail if an antenna is exposed to ice buildup or covered with snow.
The mast must satisfy the following requirements:
• The mast must be constructed of sturdy, weatherproof, noncorrosive material such as galvanized or stainless steel construction pipe.
• Antenna mast length must be sufficient to allow an antenna height at least 1.5 meters (5 feet) above the roof peak. If the roof is metal, the antenna height should be a minimum of 3 meters (10 feet) above the roof.
Antenna Polarization
It does not matter what type of polarization you choose for your ExtremeWireless antennas as long as the antenna at one end of the communications link is mounted in the same plane as the antenna at the other end.
Vertical polarization is standard for the ExtremeWireless 14 dBi directional antenna.
To minimize the influence of cross-talk between antennas, you might need to mount the antenna for horizontal polarization when:
• Multiple antennas are mounted on the same antenna mast.
• The wireless link transmissions cross another radio beam from a neighboring installation.
Approved Antennas for the ExtremeWireless APs
Extreme Networks APs using certified external antennas must comply with local laws and regulations.
An approval may be required by the local regulatory authorities. Antenna Models on page 13 lists and
describes the optional antennas that have been tested and approved for use with the APs compatible with external antennas.

Cable Installation Guidelines
The cable configuration that you use to connect an AP to an antenna varies. Use the following sections as guidelines for cabling your AP to an antenna.
Do not install the cable in tight positions, as bending or applying excessive force to the connectors may damage the antenna cable. Always allow the cable to bend naturally around corners.
The low-loss antenna cable must be secured along its complete length. Do not allow any part of the cable to hang free. This is particularly important for cable parts that are installed outdoors. The antenna cables and cable connectors are not designed to withstand excessive force:
• Do not use connectors as cable grips to pull cable through raceways or conduits.
• Do not use cable connectors to support the weight of the cable during or after installation.
• Do not use tools to tighten connectors (finger-tighten only).
ExtremeWireless™ External Antenna with Wave 2 48

7 Secure the cable along its complete length. Do not allow any part of the cable to hang free.
8 Using waterproof stretch tape, seal all outdoor connectors.
Optimizing Outdoor Point-to-Point Antenna Placement
If an AP is connected to an outdoor directional antenna, the antenna must point directly at the antenna for the other AP. A misaligned antenna can decrease the signal level or prevent communications.
ExtremeWireless™ External Antenna with Wave 2 49
Antenna Installation
Aligning an omni-directional antenna is less critical due to its wide radiation pattern. For optimal performance, make sure the antennas are properly aligned by using a pair of binoculars to point the antennas at each other.
Routine Maintenance
Routine maintenance is required for each lightning protector in your outdoor antenna installation.
Maintenance involves replacing the lightning protector at some interval depending on the lightning/ transient discharge activity in your area.
Note
Contact a local antenna installation company to determine the maintenance schedule for each lightning protector in your outdoor antenna installation.
