摘要： Electronic devices may have multiple antennas. A first antenna may be located at one end of a device and a second antenna may be located at another end of the device. An input-output port in a device may have a connector that receives a mating connector associated with external equipment. The input-output port and the second antenna may be located at one of the ends of the electronic device. When equipment such as an external video accessory is in use, input-output circuitry in an electronic device may transmit high speed data signals through the input-output port. The presence of activity on the input-output port such as video data or other data transmissions may be monitored by control circuitry in the electronic device. When input-output port activity is detected, use of the second antenna in receiving radio- frequency signals can be inhibited.
