What is AP2's antenna cable loss?

• A. 2 dB
• B. 3 dB
• C. 4 dB
• D. 5 dB

Answer: (B)

Antenna cable loss is the fixed amount of signal power that is lost as it travels from the radio to the antenna through the feed cable and connectors. For the AP-2, this documented loss is 3 dB. That means the RF power reaching the antenna is reduced by 3 dB from what the radio outputs, effectively halving the power in the path to the air. In RF planning or a link-budget calculation for this AP, you subtract 3 dB to account for this cable loss. This value is the standard specification for AP-2, and other numbers would not reflect its feed-line loss.
