Hi Kokercey,
Since I am not an expert in this field, I asked for some advice: the installer can test the cable and ensure that if he did not install it, it at least meets Hughes requirements. A note should also be made in your work order that the same coaxial cable was used so that if there is a problem with it in the future, you will not have to pay for it.
I have not checked your order notes, but since we require installation photos of work done, if there is no imaging of the trench work being done by Hughes then our technicians know it was not replaced and the same applies.
We really don't like to rip up a customer's lawn if we don't have to! :)
Thanks,
Amanda
