Chapter 3: Installing the 2480AA AP
Selecting a Mounting Location
It is very important to position the 2480AA AP and it’s antenna(s) to ensure the highest possible
data transfer speed in all kinds of weather and in all seasons. The 2480AA AP operates on a
radio frequency of 2.4 GHz and must be line-of-sight (LOS) with it’s clients. Hills, buildings,
trees and large vehicles must not block the signal path. Trees are especially troublesome as they
may allow the signal to pass easily in winter when leaves are off, but may block the signal in the
other seasons. Check the FAQ’s under “Pre-Installation and Site Preparation” or “Radio
Propagation” or “Troubleshooting” on the Telex Wireless web pages for helpful hints.

Choose a location on the roof, tower, mast or wall for your 2480AA AP and antenna(s) so that it
has a clear shot to your client base. The closest client may not necessarily have the best path if it
is blocked by hills, buildings or trees.
Ensure that the signal path to each client has sufficient Fresnel zone clearance with respect to the
ground or other obstacles near the path. Check the Telex FAQ’s under “Radio Propagation” for
more information on Fresnel zone clearance.
Ensure that your mounting location is less than 100 meters from the computer, hub, switch or
router location. (Maximum length of CAT-5 cable is 100 meters) Determine the building entry
point ahead of time to prevent problems later.
Attaching to a Mast
First, attach the top U-bolt and U-bracket set to the mast with the tabs on the U-bracket pointing
down. Attach the 2480AA AP to these tabs, then install the lower set of U-bolt and U-bracket
with the tabs up. Attach the bottom U-bracket to the 2480AA AP. Position the brackets in the
desired location on the mast, then tighten all hardware.
