Hi Nrgtic4,
We decided not to have ETI install our antenna. Instead we sent them 30' of RG58 coax cable and had them run it to an exterior Furrion outlet. We plan on stalling the antenna from a bumper mounted antenna mast and use as needed. If we had decided to have ETI install it I am sure Reace would install it with appropriate backing or support so no worries there. One last thing, the 14 feet of coax cable that came with the antenna may not be long enough for the routing with turns an all. I hope some of this is helpful to you.
Tin.
