Product Introduction
High Gain and Omnidirectional Coverage: With a 6.7dBi gain and an omnidirectional radiation pattern, the antenna provides broad 360° horizontal coverage for VHF communication systems. The high gain helps extend signal coverage and improve communication range.
Low VSWR and Standard Impedance: Featuring a VSWR of <1.5 and a 50Ω input impedance, the antenna provides good impedance matching and efficient RF power transfer. The low VSWR helps reduce reflected power and improve transmission efficiency.
Vertical Polarization and High Power Handling: The vertical polarization is well suited to common VHF communication applications. With a maximum power rating of 350W, the antenna can support higher-power transmission requirements in base station systems.
Two-Section Fiberglass Structure: The antenna features a 2-section structure with a total length of 3200mm and is constructed from fiberglass and copper. This design provides a practical configuration for fixed outdoor base station installations.
Flexible Pole Mounting and Wind Resistance: Designed for outdoor installation, the antenna supports mounting poles with diameters from 30 to 62mm and has a rated wind resistance of 50m/s. The SO239 connector also allows straightforward connection to compatible VHF communication equipment.
Application Scenarios
VHF Base Stations: Provides stable, wide-area coverage for fixed VHF communication systems.
Public Safety Communication: Supports reliable radio communication for police, fire, and emergency services.
Industrial Communication: Enables long-range VHF communication across factories, plants, and large facilities.
Remote Site Communication: Provides omnidirectional coverage for communication systems in remote and outdoor locations.

FAQ
Q: What applications is a 136-174MHz VHF base station antenna suitable for?
A: It is suitable for fixed VHF communication systems such as two-way radio base stations, public safety communications, industrial sites, and remote communication stations.
Q: How does 6.7dBi gain affect VHF coverage?
A: The 6.7dBi gain helps concentrate radiated energy in the horizontal plane, which can improve coverage distance. Actual range depends on antenna height, terrain, transmit power, and surrounding obstacles.
Q: Why is an omnidirectional antenna suitable for a VHF base station?
A: Its 360° horizontal coverage allows the base station to communicate with radios located in different directions without aiming the antenna.
Q: Can I get a sample before placing a bulk order?
A: Yes. We can provide samples for testing and evaluation, allowing customers to verify compatibility and performance before placing a larger order.
