    Small cables are cheaper Ease of installation Easier with small or short cables Note: 4RF can supply coaxial cable and connectors. Please contact your local 4RF representative or Customer Support. When running cables: Run coaxial cable from the installation to the antenna, ensuring you leave enough extra cable at each end to allow drip loops to be formed.

  • Page 15: Link Budget

    Preparation | 13 Link budget All of the above factors (and many others not mentioned) combine in any proposed installation to create a link budget. The link budget predicts how well the radio hop will perform after it is installed. Use the outputs of the link budget during commissioning testing to confirm the link has been installed correctly, and that it will provide reliable service.

  • Page 35: Management Ethernet Connection And Capacity

    Connecting to the terminal | 33 Management Ethernet connection and capacity The Management Ethernet capacity on each radio must be identical for remote communications to work and there should only be one IP connection to the management network. In the example above, the active management PC must only have one connection to the link as shown by path ".
  • Page 36 34 | Connecting to the terminal The distinction is important as: Some functions can only be carried out at the local terminal. Having different configurations at each end of the link will disrupt communications between the terminals. In these circumstances it is important to make changes to the Far end of the link first.

  • Page 37: Logging In
