METERS
Although the ATAS-J 00 is not specified for operation on the above bands, and optimum
operation is therefore not guaranteed, the ATAS-IOO generally can be tuned successfully
on these bands (some manual adjustment may be required). Operation of the ATAS-I 00 on
these bands will not damage the antenna's components; please feel free to experiment on
these bands, if you like.
