A radio station has two channels. One is \( A M \) at 1020
\( \mathrm{P} \) \( \mathrm{kHz} \) and the other \( \mathrm{FM} \) at \( 89.5 \mathrm{MHz} \). For good results

W. you will use
(1) Longer antenna for the \( A M \) channel and shorter for the \( F M \)
(2) Shorter antenna for the \( A M \) channel and longer for the \( F M \)
(3) Same length antenna will work for both
(4) Information given is not enough to say which one to use for which
