Product Introduction
Broad VHF Frequency Coverage：The GLF127 VHF antenna has a frequency range of 136 - 174MHz, making it suitable for a wide variety of VHF - based communication systems. This broad - band support ensures compatibility with different applications that operate within this frequency spectrum.
Moderate Gain with Low VSWR：With a gain of 3.5dBi, the antenna can enhance signal strength, and its VSWR of ≤1.5 indicates efficient power transfer. This combination helps in achieving a stable connection, minimizing signal loss during transmission and reception.
Durable Radome Material：The radome of the GLF127 is made of copper and stainless steel. These materials offer excellent durability, protecting the internal components from environmental factors like moisture, corrosion, and mechanical stress. This results in a longer - lasting antenna.
Versatile NMO Connector：Featuring an NMO connector, the GLF127 provides flexibility in installation. The NMO connector is widely used and easy to connect to various devices, allowing for seamless integration into different communication setups.
Wide Operating Temperature Range：Operating between - 40℃ and 80℃, the GLF127 can function in diverse environmental conditions. Whether it's in cold regions or hot climates, this antenna can maintain its performance, making it suitable for different geographical locations.
Application scenarios
Improve mobile communication for police, fire trucks, or taxis.
Enhance signal clarity for ham radio operators in remote areas.
Deploy in maritime or off-grid locations requiring reliable VHF coverage.
Integrate into emergency response systems for disaster recovery teams.
FAQ
Q: Is this antenna compatible with CB radios?
A: No, it operates in the 136-174MHz range, not CB’s 27MHz.
Q: Can it be used on a fiberglass vehicle roof?
A: Yes, but ensure proper grounding or use a ground plane kit for optimal performance.
Q: Does the NMO mount require drilling?
A: Yes, most NMO installations need a drilled hole. Use waterproof sealant to prevent leaks.
Q: What’s the maximum transmission range?
A: Line-of-sight range is typically 5-15 miles, depending on terrain and radio power.
Q: Is it suitable for saltwater environments?
A: Yes, stainless steel resists corrosion, making it ideal for marine use.
Q: Can I use this antenna indoors?
A: Yes, but outdoor mounting delivers better performance due to reduced obstructions.
Q: Does it include a coaxial cable?
A: No, only the antenna and NMO mount are included. Purchase RG-58/U or similar cables separately.
Q: How to maintain the antenna in winter?
A: Clear ice/snow buildup to prevent signal degradation. The antenna operates reliably down to -40°C.
