The SHARKIE is a compact, wideband UHF, active receiver antenna with Log Periodic Dipole Array (LPDA) structure and cardioid directivity. It's extremely low noise amplifier with easy gain setting is ideal for variable coaxial cable length attenuation compensation in the field. Rock solid mechanical construction guarantees careless functionality both in indoor and outdoor locations.
Features
- Easy gain setting with automatic last set gain storing
- Brightness of LED display can be automatically adjusted according to ambient light
- Brightness of LED display can be also set manually to requested level
- Display can be completely turned off with ability to show preset gain value upon button request
