STA 30 and 50 R

Product catalog summary

Overview
This document provides technical specifications and installation guidelines for the STA 30 - 50 R and STA 30 - 50 R/EAU rod antennas, designed for receiving applications.

Features
The antennas are constructed from solid glassfibre reinforced polyester and are available in lengths of 3 m and 5 m. They feature a passivated cast aluminium base with a bichromate finish compliant with MIL-C-5541 standards. The antennas are designed to withstand climatic conditions ranging from -40°C to +60°C and wind speeds up to 200 km/h.

Applications
The STA 30 R and STA 50 R models are receiving antennas suitable for applications such as autoalarm systems and yacht receivers, covering all bands up to 30 MHz.
