Not sure on the height requirements, but I found this mount on amazon that would fit V2 dishy, reviews even have a picture of one attached to it, so that one should be wide enough.

I plan on buying this antenna mount, do I still need to ground it and if I do do you think I can do like you did and use a splitter so the 2 wires go into 1 so I don’t waste so much wire? https://www.amazon.com/dp/B0977LQW8P/ref=cm_sw_r_cp_api_glt_fabc_PENCM228G7QEPT710N3Q?_encoding=UTF8&psc=1
