Not entirely so. Low VSWR on a transmission line means:
(a) the line is very lossy therefore the reflected power from the load
is attenuated by the loss in the line.
(b) it is terminated into a resistive load equal to the characteristic Z
of the line and there is no reflected power.
(c) it is terminated into a load containing Xl, Xc and R which approach
the characteristic Z of the line.
Only (c) above might radiate.
