TMAs vs GMAs: The Link Budget
»To determine if uplink enhancement is required a link budget is used.
»The link budget determines the balance between the uplink and downlink paths.
»TMAs may have better performance for taller towers (higher main line loss) but is there enough downlink in the link budget to support greater than 3 dBuplink imbalance?
»Use GMAs (SuperLink 830) if the link budget requires 3 dBor less on the uplink regardless of the tower height.
»Use SuperLink 830 if there is any near band transmitters that can create IMDsregardless of tower height.
