  Radio detection of air showers in the current era has progressed immensely to
effectively extract the properties of these air showers. Primary cosmic rays
with energies of hundreds of PeV have been successfully measured with the
method of radio detection. There are also attempts to observe high-energy
neutrinos with this technique. Current radio experiments measuring cosmic-ray
air showers mostly operate in the frequency range of 30-80 MHz. An optimization
of the frequency band of operation can be done for maximizing the
signal-to-noise ratio that can be achieved by an array of radio antennas at the
South Pole, operated along with IceTop. Such an array can improve the
reconstruction of air showers performed with IceTop. The prospect of using such
an optimized radio array for measuring gamma rays of PeV energies from the
Galactic Center is discussed.
