Al, You can't have your cake and eat it too... LOL! 
If you want wireless up front start with the PH-Pro 5A wireless system.
Keep in mind you go the Powercab route, you should add at least one SB5
https://ncedcc.zendesk.com/hc/...cab-SB5-Smartbooster, gives you a lot more flexibility than running the layout through the powercab. If you mount throttle bus outlets around the layout you can safely plug and unplug non-wireless throttles and everything is saved. If you want wireless, you can add an RB02 and wireless throttle and you now have two throttles, one wired and one wireless.

Thank you Casey Jones2. Does this unit have separate radio control,nothing teathered? I'd go with the 10amp unit if funds allowed now,but well we all know the end of that story.
Thank you for the info.
