KVH TVG6 ,TV6, m7 24” direct tv satellite system

Description

I bought this system to put on my boat a couple years ago and ended up buying another boat with kvh hd7 ,I purchased it from an Electronis shop that was doing a complete electronics upgrade and said this was working when removed , these are heavy and expensive to ship, I don’t know how to test it and what all the extra components are for or if they are compatible, this is being sold is, no returns , I am happy to  remove dome cover and send more pictures , it look like it’s in nice shape ....this could be a M7,TV6,TVG6, I am not sure what model it is , it is NOT a HD7
