Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right lightning arrestor depends on your specific equipment and the frequencies you use. This guide outlines the key factors to consider for effective protection.
Connector Type Compatibility
Ensure the arrestor matches your existing cable connectors such as PL-259 or N-Type to avoid needing adapters. Mismatched connectors can lead to signal loss or unstable connections.
Check your coaxial cable ends before purchasing and choose a model that supports them directly for easiest installation.
Frequency Range Support
Select an arrestor that covers the frequencies your antenna operates on. Some units cover standard bands while others support up to 6 GHz for modern cellular devices.
Verify the DC to GHz range to ensure your specific radio services are protected without signal degradation.
Impulse Capacity
A higher impulse discharge rating means the arrestor can handle larger surges from nearby lightning strikes. Look for units with ratings measured in Amps or Volts to gauge strength.
Choose a model with sufficient capacity for your area's typical storm activity to ensure long-term reliability.
Insertion Loss
Low insertion loss is critical for maintaining strong signal quality during transmission. Units with loss under 0.5 dB are generally preferred for high-performance setups.
Review specs to ensure the arrester does not significantly attenuate your transmit or receive power.
Grounding Requirements
All arrestors require a solid connection to earth ground to function correctly. Ensure you have a proper grounding wire and rod system ready before installation.
Check if the unit includes a ground lug or if you need to purchase grounding hardware separately.
Replaceable Elements
Some premium models offer replaceable gas discharge tubes allowing you to maintain the unit after a strike. This feature extends the life of the device and saves money over time.
If you live in a storm-prone area consider a model with a replaceable core for continuous protection.
Build Durability
Outdoor rated units should have corrosion-resistant materials like nickel-plated brass to withstand weather exposure. Durable construction ensures the unit functions properly over years of use.
Look for weatherproof ratings if your installation is exposed to rain or extreme temperatures.
Power Handling
If you use amplifiers or high-power transmitters ensure the arrestor can handle your power levels without overheating. Higher wattage models are available for demanding setups.
Check the maximum power rating to ensure it matches or exceeds your station's output power.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor inline between the antenna and the coaxial cable entering your equipment. Ensure the connections are tight to prevent signal leakage or water intrusion.
Connect the grounding terminal to a dedicated earth ground rod using a heavy gauge copper wire. This path is crucial for diverting dangerous surges away from your gear.
Regularly inspect the unit for signs of corrosion or damage especially after severe storms. Replace any damaged parts immediately to maintain protection effectiveness.
Frequently Asked Questions
Do antenna lightning arrestors stop all damage from lightning?
No arrestor can guarantee 100% protection against all lightning scenarios. They are designed to divert most surges to ground but extremely direct hits may still cause damage. Using a combination of lightning rods and disconnecting gear during storms offers the best defense.
Is a ground wire included with the arrestor?
Most lightning arrestors do not include a ground wire. You will need to purchase a grounding cable separately to connect the unit to your earth ground system. Always check the product details before buying to ensure you have the necessary parts.
Can I use a 50 Ohm arrestor for a 75 Ohm system?
It is generally recommended to match the impedance of your system for optimal signal performance. Using mismatched impedance can lead to signal reflections and reduced quality. Choose an arrestor designed for your specific cable impedance.
How do I know if my arrestor is working after a strike?
Most arrestors do not have visual indicators. If you suspect damage inspect the unit for physical signs like burn marks. Consider using a model with a replaceable element or testing signal quality to ensure it is still functioning correctly.
Do these protect indoor equipment or just outdoor antennas?
These devices protect both by diverting surges before they enter the building. However they must be placed near the entry point to be effective. Proper installation ensures your indoor radios and amplifiers stay safe.
How often should I replace my antenna lightning arrestor?
There is no set timeline but it is wise to inspect the unit annually. If it has absorbed a major surge or shows signs of wear replace it immediately. Regular maintenance ensures it functions properly when needed.
Final Thoughts on Choosing the Best Antenna Lightning Arrestor
The Proxicast ProGrade SP1000 and RAIGEN models stand out for their balance of performance and features. Each offers robust protection suitable for different types of antenna systems and user needs.
Prioritize connector compatibility and proper grounding when selecting your unit. A high-quality arrestor installed correctly will provide years of reliable service for your equipment.
Remember to check current prices and availability before purchasing as offers may change. Invest in a quality solution to keep your communication gear safe from unpredictable weather.
