titleNOTE

Any external antenna of the same type and of gain not greater than the one approved by the FCC can be used with the InfiMAN Evolution/InfiLINK Evolution E5-BSE in the countries abiding by the FCC Rules.

External antenna must be professionally installed pursuant to the section 15.203 of the FCC Rules.

To mount and connect an external antenna to the InfiMAN Evolution/InfiLINK Evolution E5-BSE ODU, proceed as follows:

  1. Mount the antenna(s) according to manufacturer’s instructions;
  2. Connect the ODU V and H N-type interfaces to the antenna(s) with RF coaxial cables and with appropriate connectors. Use cables not longer than 3 m (9.8ft). Tighten the N-type connectors to a torque setting of 1.7 Nm (1.3 lb ft);
  3. Form drip loops near the cable ends at the ODU’s side so that water doesn’t creep towards the ODU connectors;
  4. Weatherproof the N-type connectors (when antenna alignment is complete) using PVC tape and self-amalgamating rubber tape;
  5. Weatherproof the antenna connectors in the same way (unless the antenna manufacturer specifies a different method);
  6. Fix the antenna cables to the supporting structure using site approved methods. Ensure that no undue strain is placed on the ODU or antenna connectors. Ensure that the cables do not flap in the wind, as flapping cables are prone to damage and induce unwanted vibrations in the supporting structure.
Warning
titleCAUTION

Please note that the pressure equalization system in Infinet devices is performed via gas exchange through a cable gland and Ethernet cable jacket with a dry room where the power supply is installed. In order to avoid ODU failure due to moisture entering the device, for example, during the pressure drop during the rain, the cable gland assembly requirements should be met and there are should be no cracks in the Ethernet cable jacket.

In addition, you should avoid the Ethernet cable bending near the ODU and pinching with clamps, that can bring to the pressure equalization system fault between the internal volume of the sealed ODU and the external environment during a sudden air temperature change. This may lead to the leakage and device failures.
