The invention allows enhancing radio signal coverage in an elevator environment. An elevator antenna pair comprises a primary antenna that is configured to transmit and receive radio frequency signals with an external wireless communication network. The elevator antenna pair further comprises a secondary antenna that is communicatively connected to the primary antenna and configured to transmit and receive radio frequency signals with at least one radio frequency transceiver in an elevator car. The primary antenna is arranged within an elevator landing signalization unit, and the secondary antenna is arranged inside an elevator hoistway.
