DAB LOGPERIODIC ANTENNA
The main feature of this antenna is the high suppression of the side lobes as well as the extreme cleanliness of the radiation pattern.
This type of antenna is particularly suitable for use in collinear systems where it is essential to have high front-to-back and front-to-side ratios. Available in stainless steel versions (cradle and elements) or stainless steel with anticorodal aluminum elements. The two versions are produced as standard with Nf (500W) or 7/16 "f (1.500W) connector.
