Best is a feed-through or barrel connector with a blue core vs. white. Red many work. White is not rated for separator (band stacked) frequencies but will work short term.
On my second 722 install they would not let me keep my working wall plates with white one--or they would walk away without leaving the receiver. I had to go back and replace the raw cables coming through the wall-plate with the larger reversed-to-fit blues barrels.
