Note: We suggest clients use our standard antenna accessory part, because it is special design for this system, High gain and special Frequency range choose .

 

  1. Important Notice:

Do not plug-in the power, only after install all cable and antenna, and check it installed correct.

Make sure, your outdoor antenna installed at open area , not shield by tree or high building , and make sure there is no shield at the direction to the satellite.

  • Fix and install the outdoor antenna.

The outdoor antenna must be installed vertically, signal performance will be degraded if the antenna is not vertical . make sure the outdoor antenna fix strongly.  Above have mentioned the important notice about the outdoor install problem. Seal the RF cable joint to avoid rust caused by water leakage, which resulted SWR in be-coming bad and influence using.

  • Connect the 10m RF cable to the outdoor antenna. It is better fix the cable well along with the wall . and do not let it all over the place. Avoid people go and stumble for incaution.
  • Fix the amplifier device main unit at the suitable location .

  1. Frequently asked questions
  • No satellite signal at the satellite phone after installed.

The reason maybe as below :

  2. Please check whether you plug-in the DC power supply .
  3. Indoor antenna should installed at overhead, which can cover more area .

 

The reason of self-excitation phenomena : The isolation degree of antenna is not enough. To reduce the self-excitation phenomena , you need enlarge the isolation degree by increase the distance of indoor antenna and outdoor antenna , and also should isolated with wall or windows or door . if isolated by windows or door , please confirm it is closed not open , if you have to open it , you need install the outdoor antenna more high
