Default 1.2 GHZ collinear array

I want to build a 1.2 Ghz antenna for this tiny wireless camera receiver
I have. The antenna on it uses an F connector so I am guessing it is a
75 ohm antenna. I have seen several web pages with a collinear design
using 50 ohm coax cable. If I use some 75 ohm cable TV coax to make the
antenna do I need to do anything else to match the antenna to the 75
ohms of the RX? Also does anyone know what eh velocity factor for the
coax the cable company uses is?
