Power Handling: 1000 W Average
Modular and Easy-to-Install
Long-Range and Mid-Range Communications
Valcom's VBBA-NVIS antenna is specifically designed for long range HF communications using near vertical incident skywave (NVIS) techniques. This antenna can be used where traditional surface wave propagation is not practical by means of a traditional whip antenna, due to range requirements or terrain difficulties.
The antenna is based on Valcom's field-proven VBBA2-30 model broadband antenna. With the use of high-strength fibreglass supports, the antenna is mounted horizontally to provide an NVIS capable radiation pattern. The structure is extremely rugged and is built to survive severe environmental conditions in a permanent installation.
The VBBA-NVIS antenna is broadband in nature and provides a maximum VSWR of 2.5:1 without the need of an external tuner. An optional vertical whip attachment widens the antenna's vertical pattern to provide uni-directional mid-range communications.
The VBBA-NVIS is supplied with all the necessary parts and hardware for an effortless installation
