Dual Directional amplifiers (active repeaters) are designed primarily for inside buildings, tunnels and poor signal locations where other methods of signal enhancement are either impractical or uneconomical.
Each model consists of two bandpass duplexers and two amplifiers, and will maintain signal level over cable runs that have high attenuation.
This unit employs low noise figure amplifiers and high Q filters for superior performance.
In-field alterations are easlity effected by the modular nature of the design. These duplexers are supplied pre-tuned, however they are field tunable within the nominated band. | | | |
| All models are manufactured utilizing 19'' rack mounting brackets for ease of installation. | | | |
An Automatic Gain Control circuit with a dynamic range of 30 dB may be incorporated to order.
Fully enclosed weatherproof stainless steel housings are available for external applications. | | |
