I'm in the process of adding a second DSC 1832 accessory cabinet that has a DSC 5204 power supply to power 3 ptk5700 touch keypads, backup battery and IT-100 serial module to connect to the Lutron RadioRA2 main repeater. There's plenty of room in the panel to accommodate the Lutron RadioRA2 main repeater. I can have the antenna exposed -- the repeater is currently in the location exposed and working fine. Do you guys think this would work inside the cabinet? If so, it would be a very clean install with no exposed components and cables. Or do you think there would be too much interference with the alarm power supply and components? Also, is it possible to mount the antenna separately from the Lutron RadioRA2 main repeater?
