3.5.1 Pre-Climb Checklist and Set-up
The following information may be used as a basic PathAlign-R checklist for technicians prior to
climbing the antenna tower. A copy of this list may be found in the User Information Card that
was included with the PathAlign-R. This check list is in addition to any safety issues regarding
personnel and equipment that may be relevant. Safety issues regarding personnel and
equipment are beyond the scope of this manual.
1. Review the Engineering Profile to determine the expected RSL (received signal level, or
path loss) for the link under test (this should include the free space path loss and the
gain of the antennas). Note: The loss exhibited by the installed cable or waveguide
transmission lines should be included in this figure if you are connecting the PathAlign-R
through these lines. When connecting the PathAlign-R directly to the back of the
antenna with a short coax cable the insertion loss is minimal.
2. Both tower technicians should go over their check lists, prior to climbing the tower, to
assure that, included with the Path Align-R, they have:
•
A charged battery installed! (possibly a spare if you are planning to be up for over
4-5 hours);
•
The proper waveguide-to-coax adapter for the antenna;
•
A coax cable (SMA to appropriate coax connector on the waveguide adapter);
•
The supplied headset; and,
•
A carabiner and a nylon runner of appropriate length to attach the bag strap to
the tower.
3. Set one PathAlign-R unit to ‘Master’ and the other PathAlign-R unit to ‘Slave’ (it does not
matter which is which, as long as they are different).
4. Using the front panel thumbwheel switches, select the proper link frequency (Note: both
units must be set to the same frequency, e.g., 6.200 GHz).
3.5.2 Antenna Path Alignment Procedure
The following procedure may be used as a guide in path alignment when utilizing the PathAlign-
R test sets. A copy of this procedure may be found in the User Information Card that was
included with the PathAlign-R.
1. After reaching the antenna, check that the antenna polarization is properly setup
(polarization should be the same for both transmitting and receiving antennas).
2. Locate each PathAlign-R unit near the back of the antenna.
3. Attach the coax-to-waveguide adapter at the back of the antenna’s waveguide flange.
4. Connect the coax cable from the appropriate output connector on the Path Align-R to the
adapter.
5. Connect the headset to the Path Align-R.
