  In this work we give a few new Strichartz estimates of radial solutions to
the wave equation. These Strichartz estimates still use $L^p L^q$ type norms in
each channel-like region $\{(x,t): |t|+2^k < |x| < |t|+2^{k+1}\}$, with weaker
restrictions on $p, q$ than the classic ones, but combine these localized norms
together in the way of an $l^2$ space. We also give an application of these
Strichartz estimates on the well-posedness theory of non-linear wave equations.
