118-136MHz Side Mount Dipole, Stainless Steel

Stainless Steel Air band side mount dipole


The SMAS (Stainless Steel) is a unity gain broad band base folded dipole antenna. It covers the entire range from 118 MHz to 136 MHz. It is supplied with a standard boom length to facilitate ¼ wave antenna to mast spacing. The dimension is taken from the centreline of the dipole element to the mast face.

The antenna array is DC grounded for lightning protection and is vertically polarised and can be stacked in different configurations to give desired gain and field patterns.
