TWIN TMA 1900
Designed to be used at co-located 700MHz/850MHz and 1900MHz sites, the Kaelus TMA2061 provides gain on the 1900 uplink path while diplexing the 700MHz band to avoid costly external diplexers. Separate feeders are no longer required, resulting in decreased hardware costs, environmental impact and tower licensing fees.
FEATURES
- Full band 1900 TMA with 698-960MHz bypass path
- Provides improved base station sensitivity through low noise figure and good linearity
- High reliability with full lightning protection and a fail-safe bypass mode
- Small twin unit, ideal for X-Pol dual band systems
- AISG 2.0 compatible with current window alarm backup mode
- High power handling
