Length is a factor to determine the attenuation of a cable. So, have an accurate measurement of length and attenuation and watch out carefully.

Before buying coax cable carefully check the connectors. Does it have the standard PL 256 connectors? If yes then move on to the next step. Check out the quality of the connectors. The good quality connectors are:
