Product Description
A
Folded Stack Dipole Antenna is a
multi-element, vertically stacked dipole antenna designed to provide
omnidirectional coverage in the horizontal plane. Each element is a
folded dipole, which improves bandwidth and impedance matching compared to a simple dipole. The stacked arrangement increases gain and signal strength while maintaining a uniform 360A radiation pattern.
High Performance at VHF FrequenciesOptimized for a broad frequency range between 136-174 MHz, this folded stack dipole antenna delivers omni-directional coverage, making it suitable for a wide variety of two-way radio communications. With two stacked dipoles, the design maximizes gain while maintaining 360 horizontal coverage, ensuring reliable connectivity over distances up to 20 km, depending on installation height.
Rugged Design for Extreme EnvironmentsBuilt using corrosion-resistant aluminum alloy, brass, and reinforced fiberglass, the antenna withstands harsh environmental conditions. Rated for wind velocities up to 200 km/h and operational temperatures from -40C to +60C, it is ideal for outdoor deployment in urban, rural, or remote settings across India.
Effortless Installation and ConnectivitySupplied with a mast mounting clamp and an N-type female connector at the bottom, the antenna allows for quick, secure installation and easy cable management. Its 50 ohms impedance ensures compatibility with standard VHF radio systems, while DC grounding provides integral lightning protection.
FAQ's of FOLDED STACK DIPOLE ANTENNA (OMNI DIRECTIONAL):
Q: How do I install the folded stack dipole antenna for optimal performance?
A: Mount the antenna vertically on a stable mast using the included clamp. Ensure it is installed at the highest feasible elevation to maximize the talk range, which can reach up to 20 km depending on height and surrounding terrain. Always follow local safety regulations during installation.
Q: What benefits does the omni-directional radiation pattern provide?
A: The omni-directional, 360 radiation pattern ensures consistent signal coverage in all horizontal directions. This makes the antenna ideal for base stations or repeater sites serving users distributed in various directions without the need for realignment.
Q: What environments is this antenna suitable for?
A: Designed to withstand extreme weather, the antenna operates in temperatures ranging from -40C to +60C and can handle wind speeds up to 200 km/h. It is well-suited for urban, industrial, coastal, and remote outdoor installations across India.
Q: How does the antenna offer lightning protection?
A: It is DC grounded, which helps mitigate the risk of lightning damage by providing a direct path to ground for electrical surges, enhancing equipment protection and operational safety.
Q: What is the maximum power input and compatibility of the antenna?
A: The antenna supports up to 500 Watts maximum input power and features a 50 Ohms impedance, making it compatible with standard VHF radio transmitters. It is fitted with an N-type female connector located at the bottom for reliable connections.
Q: What is the process for maintenance and upkeep?
A: Routine maintenance involves checking the mounting hardware for tightness, inspecting the antenna for physical damage or corrosion, and verifying the integrity of cables and connectors. Minimal maintenance is needed due to its durable construction materials.
Q: Where can I purchase the folded stack dipole antenna in India?
A: The antenna is available through authorized distributors, manufacturers, suppliers, traders, and wholesalers across India. Look for reputable suppliers with experience in communication infrastructure equipment to ensure product authenticity and technical support.
