The Sirio GP 108-136 LB U UHF base antenna is designed for users who expect maximum reliability within the 108–136 MHz frequency range . This wideband base antenna combines robust construction with stable performance and is designed for fixed installations where continuity is essential.
As a 1/4λ ground-plane antenna, this base antenna for the UHF band provides an omnidirectional radiation pattern. This ensures even signal distribution throughout the installation – ideal for situations where communication takes place in multiple directions. Thanks to the linear vertical polarization, the signal transmission remains clear and consistent.
Reliable performance under all conditions
With a power output of up to 1000 watts (CW) at 30°C , this UHF base antenna is built for professional use and long-term operation. The unity-gain configuration (0 dBd – 2.15 dBi) ensures stable and predictable coverage without unwanted radiation pattern distortion.
The integrated DC ground protection prevents damage from static discharge. This increases the safety of your installation and contributes to a longer lifespan of connected equipment.
The design is fully optimized for outdoor use. The antenna is made of anodized aluminum, combined with stainless steel mounting hardware and durable nylon components. This makes the Sirio GP 108-136 LB U highly resistant to rain, wind, and other harsh weather conditions.
