With a one meter loop, a capacitor with a value of 100 pf

A 80 cm loop gives me reception between about 5 and 12 Mhz, this is with
a cap from a FM/AM radio kit ...

So, to have higher freq, the loop should be made smaller ... (or higher
cap ?..)
Make the cap smaller. You can if you put a similar cap in series with
the first you will reduce the total capacity and raise the resonant frequency.
Changing loop length is too much trouble, changing a cap is easy.
