Abstract: A vehicle holder with a wireless signal enhancement function is provided. A receiving antenna and a transmitting antenna are disposed on a holder. The receiving antenna is pivotally connected to the holder, and it may rotate relative to the holder to be adjusted to an optimal signal-receiving position. The wireless signal received by the receiving antenna is transmitted to the transmitting antenna directly, and then the transmitting antenna transmits the signal to a wireless communication device disposed in the vehicle holder in a wireless mode. Thus, the quality of the signals, especially GPS signals, is improved.
