SUPER HIGH POWER

These models, due to their extremely high power capability, require heat sinking. This should be done at the bottom surface of the attenuator which is unpainted. Although not mandatory, it is also recommended that a blower be utilized, when available. Other models having higher attenuation can be quoted. For such requirements, please contact the factory direct. Also, as these units are supplied with a micrometer control, a calibration chart may be supplied at any designated frequency at an additional charge.
