Duck69 The V572A comes less the PSC05 and the V572AB comes with it. The unit won't handle any of the security signals so theres no help with RF from that end. My V572AB solved all my RF problems and even worked very well with the RF stick-up switches.
I turned off all the transcieved codes in the CM15A except the ones the security sensors use and have had no problems with the 2 colliding. The antenna is a quarter wave and in my application I found it worked best mounted horizontal rather then vertical. Brian's right about it being able to be programed with a serial port connection. When you run the software program you can check or uncheck each house code you want the unit to respond to. My unit came with all house codes enabled by default and I left it that way. Hope this helps.
