8dbi gain LORA Low frequency Fiberglass Omni Antenna

Product Introduction

1. Specialized Frequency Band: Engineered for the 390 - 440MHz frequency range, it's an ideal fit for LORA low - frequency applications, ensuring precise and stable signal transmission.

2. High Gain: Boasting a gain of 8 dBi, this antenna significantly enhances signal strength, enabling long - range communication with reduced signal degradation.

3. Omni - directional Coverage: With a 360° horizontal beamwidth, it provides all - round signal distribution, making it suitable for scenarios where signals need to reach multiple directions without adjustment.

4. Sturdy Fiberglass Build: Constructed from fiberglass radome material, it's highly durable, resistant to environmental elements like harsh weather. It can operate within a temperature range of - 40°C to 60°C and withstand a rated wind velocity of 60 m/s.

5. Convenient Connector: Equipped with an N female connector at the bottom, it allows for easy and secure connection to various LORA devices, simplifying the setup process.

6. Lightning Protection: The DC ground lightning protection feature safeguards the antenna and connected equipment from electrical surges caused by lightning, ensuring long - term reliability.

   
   

Comparison of GL400V-6 and GL420V-8 LoRa Fiberglass Omni Antennas

Key Differences

1. Frequency Range:

• GL400V-6 supports a wider range (380–450 MHz), making it suitable for applications requiring lower frequencies .

• GL420V-8 is narrower (390–440 MHz) but covers common LoRa bands .

2. Gain:

• GL420V-8 offers higher gain (8 dBi vs. 6 dBi), providing better signal reach and penetration.

3. Size and Weight:

• GL400V-6 is shorter (1250 mm) and lighter (1.5 kg), ideal for compact installations.

• GL420V-8 is longer (2230 mm) and heavier (2.5 kg), requiring sturdier mounting.

4. Application Flexibility:

• GL400V-6 is better for environments with space constraints or lower frequency requirements.

• GL420V-8 is preferred for maximizing coverage distance in standard LoRa bands.

Recommendation

• Choose GL400V-6 :

• Your LoRa devices operate below 390 MHz or require a compact, lightweight solution.

• Installation space is limited (e.g., urban areas or portable setups).

• Choose GL420V-8 :

• Your application uses frequencies within 390–440 MHz and prioritizes signal strength/range.

• Mounting stability (e.g., tall towers) and wind resistance are manageable.

FAQ

Q:What is the maximum input power the GL420V - 8 antenna can handle?
A:The maximum input power is 100W.

Q:Can it be installed outdoors easily?
A:Yes, with appropriate mounting hardware for poles with a diameter of 35 - 60 mm and its user - friendly N female connector, outdoor installation is straightforward.

Q:How well does it perform in extreme temperatures?
A:It can operate in temperatures from - 40°C to 60°C, ensuring reliable performance in both cold and hot environments.

Q:Is it compatible with all LORA devices?
A:It operates in the 390 - 440MHz frequency range. While it should work with most LORA devices within this range, it's best to verify compatibility.

Q:What's the advantage of the 30° vertical beamwidth?
A:The 30° vertical beamwidth helps focus the signal in a specific vertical area, optimizing signal transmission and reception for better performance in different installation heights and scenarios.

Q:How does the lightning protection feature affect the antenna's lifespan?
A:The lightning protection diverts electrical surges, preventing damage to the antenna from lightning strikes, thus significantly extending its lifespan.
