I first saw the Radio Dock several years ago during a visit to Juggernaut’s HQ. While they’ve been offered to various programs, they’ve never been a standard product, until now. 
The Radio.Dock was designed to attach directly to the PALS webbing on armor to house any bottom-battery tactical radio in the inventory (148/152 style battery). The Radio.Dock™ utilizes a rugged battery eliminator with capability to be power-only or power/data capable. Thales even uses it with their 148’s with Mission-Modules on the back. The open configuration effectively allows all of the data-sidehats to stay attached and the face of the radio to be protected while allowing much of the radio housing and the top half of the battery housing to stay exposed for conducting heat off the radio (very critical). The radio is secured via the patent pending PPIP and BOA-Closure System allowing the user to pivot the radio away from the armor to interface with the display/control on the faceplate.
The Radio.Holster on the other hand is a sub-$100 alternative to the Radio.Dock for those who don’t need a data connection. It still has the PPIP and Boa-Closure System with a ‘battery-cup’ rather than the bayonet features used on the Radio.Dock™ to create the Radio.Holster™. 
Both are PALS compatible. Available from www.juggernautcase.com
