Air band 4-stack dipole array, 304 stainless steel, 118-137MHz, 250W, 7.5dBd – 7.0m

Air band 4-stack dipole array, 304 stainless steel, 118-137MHz, 250W, N-type female, internal power divider, 7.5dBd - 6.0m

Product code: S4B42-1CSS

The S4B42-1CSS stacked dipole array antenna consist of 4 folded dipoles phased with an internal power divider, configured in a vertical dipole array. This results in a true broadband coverage of the entire Air band 118-137MHz frequency, high gain performance at 7.5 dBd and effective performance at better than 1.5:1 VSWR. The S4B42-1CSS dipole binary array is a fixed position dipole array antenna for ground-to-air communications, suitable for either a civillian or military installation. The S4B42-1CSS dipole array is ideally mounted using a bottom, central and top mount clamp to ensure no mechanical movement or flexing of the boom.
