Which has longer period of revolution, a satellite revolving close to or away from the surface of the earth?

The time period of a satellite revolving around the earth surface is,

\[T=2π\sqrt{\frac{(R+h)^3}{GM}}\;\;\text{or}\;\;T=\frac{2π}{R}\sqrt{\frac{(R+h)^3}{g}}\]

If the satellite is revolving away from the surface of the earth, $h$ will be more. So, the time period will be more. Hence, the satellite revolving away from the surface of the earth has longer period of revolution.
