Valcom's VGPA30-108 antenna is a ground plane antenna designed to operate in the VHF frequency band from 30 MHz to 108 MHz. The antenna's internal loading coil and adjustable vertical element provide vertically polarized, omnidirectional radiation in the azimuth plane with an available power handling capability of 80 watts.

​

The VGPA30-108 boasts a maximum VSWR of 3.0:1 across the operating band. However by adjusting the four telescoping sections of the element, efficient, low-power transmissions can be achieved with an average VSWR of 2.0:1. The antenna also operates well, unadjusted, for use in broadband receiving and scanning applications.

​

The VGPA30-108 is lightweight, rugged, and quick and easy to assemble, which makes it ideal for mobile or temporary field communication applications. Its design allows for mounting atop a VIXAM-40 Telescoping Mast, although the 7/8 inch spigot can be installed just about anywhere.

​

During transport or storage, the VGPA30-108 efficiently collapses for storage within a rugged, compact canvas sack.
