3. Enter start and stop azimuth value in degrees for the blocking zone. Values allowed: 0 to
360 degrees. Enter clockwise.
4. Enter the start and stop elevation angle for the blocking zone. If you enter nothing,
there will be no blocking zone. Values allowed: -30 to 90 degrees.
5. Select
No TX
for zones if you don’t want the system to transmit.
If not selected, the system also transmits when pointing through areas with blocking
objects. The modem will shut off for TX if no signal is received.
6. Click
Apply
to save the blocking zones.
Figure 6-19: Blocking zone, example: 315 - 45 degrees
Figure 6-20: Blocking zone, example: 45 - 315 degrees
Important
You must enter 2 different elevation angles to have an active blocking zone.
Note
If a blocking zone is defined with TX allowed ( No TX not checked), the modem
is not informed about the blocking zone.
Modems may react differently when informed about a blocking zone, this has
influence on recapturing the link. The worst case is that the modem will search
the entire list of available satellites and frequencies when unaware of the
blocking zone, resulting in prolonged down times until the link is recaptured.
For optimum performance it is recommended to check
No TX
