| Description: | The Valcom model VBBA 2-9
is a 35-foot, broadband HF tactical whip antenna. The VBBA 2-9
operates in the 2 MHz to 9 MHz range with a maximum VSWR of
2.5:1. The VBBA 2-9 was designed to match all of the physical
and environmental characteristics of Valcom's highly successful
antenna model VBBA 2-30. As with the VBBA 2-30 model, the VBBA 2-9 is designed to match the full operable frequency band without the use of an external tuning device or by having a purely resistive element in or at the base of the antenna. This translates to a higher gain and lower VSWR over the band. Further, by offering a narrower, more specific frequency band, the VBBA 2-9 is able to perform with even better expectations. The VBBA 2-9 is a self-supporting whip antenna, comprised of an aluminum radiating element, and an integral fibreglass mounting base and insulator. The mounting base utilizes the same base mounting pattern as the AS-3772B/U tunable HF shipboard antenna. |
| Notes: | 1. Do not use lead base paint to touch-up or repaint antenna |
