Aligning the Antenna

2.8 Aligning the Antenna
The TR2526+ is equipped with an audible alignment aid that simplifies the setup process. It
permits alignment to the hub site without the use of the cable modem or any test
equipment. It consists of a level detector for the full receive band and an audible beeper
sealed into the unit that sounds at a rate that increases with increasing signal level.
The detector operates over a wide signal level range. Installations that are closer to the hub
site and consequently receive a higher signal level will have a faster beep rate than an
installation further out. In each case, finding the alignment with the fastest beep rate
indicates the best alignment.
Signal Strength and Alignment:
1) Mount the TR2526+ and the antenna as described in “2.2 Mounting the TR2526+” on
page 4 and “2.3 Mounting the Antenna” on page 5. If the antenna is difficult to tilt or
turn, loosen the antenna mounts slightly.
2) Apply power to the TR2526+. The beeper will begin beeping as soon as power is applied.
3) Point the antenna in the general direction of the hub site, then fine tune the alignment
by moving the antenna slightly in both directions to maximize the rate of the beeper. A
fast beep rate indicates a high quality signal, a slow beep rate indicates a poor quality
signal. The fastest rate represents the highest receive signal level and the best
alignment.
4) Once you have optimized the alignment, tighten the antenna mount to secure it to the
pole. The beeper will automatically mute between 1 and 7 minutes after the unit was
powered up, turning off sooner with higher received signal level.
To reset the beeper:
1) Unplug the power supply from its AC connection.
2) Wait 5 seconds and plug the power supply back into its AC connection. The beeper will
begin beeping as soon as power is available.
Note: The TR2526+ alignment aid does not discriminate between signals in the receive band. If
signals other than those from the hub are present, this could result in a misalignment. In this case, a
conventional alignment technique would need to be employed.
Note: Before aligning the antenna, ensure that the cable modem is not connected to the power
inserter. The cable modem signal may prevent the audible alignment aid from responding to very weak
receive signals.
