* Measured value varies depending on how to have MSA338(E/TG)/358 main unit. Moreover, if the person who has is different, measured value will vary. Because M305/307 is 1/4 λ whip antenna. Therefore, in the measurement used an antenna M305/307, measurement errors occurs. The error value is several dB or 10dB or more. - Page 48 180° * All the data are those when the antenna is connected to the RF input with no obstacles around. * However, data of M305/307 is reference data of the conditions in which people have MSA338(E/TG) /MSA358 attached M305/307.
