Go to SETTINGS > Blocking zones, select Boom and read the “Current azimuth” at
the top - this is the low azimuth limit of the boom blocking zone. Type it in as the first
Azimuth value and click Apply (but not Active).
Go back to the Jog page.
b. Boom blocking zone, elevation high limit: Jog to the lowest elevation angle that
allows the antenna to move all the way past the object in Azimuth. Go to the Blocking
zones page and read the “Current elevation” - this is the high elevation limit of the
boom blocking zone. Type it in under Elevation and click Apply. If the antenna is
completely blocked, use 100 Deg when you type in the blocking zones. Go back to the
Jog page.
c. Boom blocking zone, azimuth high limit: Jog the antenna counterclockwise
(decreasing azimuth) as close as possible to the blocking object, and so that the antenna
can move freely in Elevation without touching the object. Go to the Blocking zones
page and read the “Current azimuth” - this is the high azimuth limit of the boom blocking
zone. Type it in and click Apply. Go back to the Jog page.
5. Jog the antenna at least 5 degrees away from any blocking zone.
6. Define the dish blocking zones as follows: (see Figure 8)
Figure 7: Web interface, Boom blocking zones
The elevation set in the Blocking zones page is the elevation of the signal
beam. Some parts on the antenna may be below the elevation angle (e.g. the
Forward Wave Guide), so you should add a little margin to keep all antenna
parts clear of the object(s).
