Glad you got one.
You might need to get another backshell if they did not include the little bars to grip the cables. Very important to make sure you have solid operation of the unit.
Here is a link to one on eBay.

Also someone on here gave me the eBay seller wifi_expert for BNC cables. You might get lucky and the pig tail on that tray connect up then again you might not.
