A door and method of constructing a door whereby a security system antenna is routed through channels that are incorporated within the outer perimeter of the door, and completely or partially hidden from sight. The channels are sized to retain at least a portion of the security system antenna therein. The door can be purchased with the antenna wires already embedded therein and hidden from sight and installed at a facility without the need to mount the antenna wires on a pedestal or dig up floors and/or walls to embed the antenna coils. Existing doors can be retrofitted to install the antenna wires. Such antennas may be used, for example, in an RFID marker system or a magneto-acoustic EAS marker system.
