That depends on where you put it. A mailbox could be anywhere.
As quoted from the USPS website: "You should install the mailbox with the bottom of the box at a vertical height of between 41-45 inches from the road surface."Your house number should be clearly marked on the mailbox with painted numbers or stickers no less than 1" high. The numbers should be placed on the side of the box visible to the carrier's regular approach. The mailbox may also have the owner's name.The box should be on the right-hand side of the road as traveled by the mail carrier.It should be located approximately 2' from the side of the road to ensure the carrier can get off the road enough to clear traffic.

One method to extract the intelligence (signal) from a high frequency carrier in FM receivers is with a phase locked loop.
