Answer

Also vertical.

Work Step by Step

Like the transmitter’s antenna, the receiver’s rod antenna should also be vertical, to obtain the best reception. The transmitted EM wave has its oscillating electric field in a vertical plane, so a vertical receiving antenna would do much better. The electrons in the receiving antenna would have a long vertical path to oscillate up and down, boosting the signal.
