Flat ribbon f connector satellite cable.

Hi, have any of you got this for feeding through caravan window. It is supposed to anable you to shut the window without distorting the window rubber. We dont want to drill holes to feed satellite cable through to the inside of the caravan and saw this advertised and thought it might be a good idea but thought we would ask you lovely people to see if you had any good comments (or bad) to make first of all.

Thanks in anticipation.
