How should the PTP 49400 4.9GHz Backhaul TX power

How should the PTP 49400 4.9GHz Backhaul TX power settings be set to when using a connectorized antenna?

In order to comply with regulatory power limits, the TX power must be backed off when using an external antenna with a gain greater than 26dBi. For example, when using a 33 dBi antenna the TX power must be backed off from 23dBm to 16 dBm in order to not exceed 26 dBi.
