I have a Cobra 75 WX ST. I installed the controller box under the seat. It works well and only took about an hour to install and run wiring. I saw it on the internet for $93 but I couldn't tell you where. I followed Ian's example for the antenna mount and it worked like a dream. The only thing I did different is put a zip tie that is loosened over the antenna so it wouldn't flip up during driving. Go to www.xterrajournal.com it will show you the mount for the antenna.
