Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right arrestor depends on your equipment and frequency band. These factors help you match specs to your setup.
Connector Type
Match connectors like N-Type or SO-239 to your coaxial feedline. Using mismatched connectors requires adapters that can add signal loss or weaken protection.
Choose the arrestor with connectors matching your existing antenna and radio setup.
Impedance
Most systems use 50 Ohm impedance, but TV often uses 75 Ohm. Mismatched impedance causes signal reflection and weakens your transmission.
Verify your equipment specs and select an arrestor that matches that value exactly.
Frequency Range
Ensure the device covers your operating frequencies. A unit covering DC to 6 GHz handles both cellular and Ham effectively.
Select a model that covers your full range without sacrificing performance.
Insertion Loss
Look for low insertion loss values under 0.5 dB to keep your signal strong. High loss weakens transmissions and affects data throughput.
Choose a model with low loss to ensure quality signals during storms.
Grounding Requirements
A surge arrestor only works if properly grounded. Most require a separate ground wire to divert surges safely.
Ensure you have a ground wire and know how to install it before buying.
Replaceable Components
Some models feature replaceable gas tubes, allowing reuse after a major strike. Others need total replacement.
Consider a model with replaceable parts for long-term cost efficiency.
Build Quality
Look for brass plating and weather-resistant coatings for outdoor durability. This ensures the device survives years of exposure.
Choose a unit with sturdy plating to withstand harsh weather conditions.
Power Capacity
High-power setups need arrestors rated for higher wattage to avoid internal burnout.
Check the power rating and ensure it exceeds your transmission output.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor as close as possible to where the cable enters your building. This shortens the path lightning might take to reach your equipment.
Securely connect a ground wire from the arrestor's grounding lug to your earth ground system. Ensure the connection is tight and free of corrosion for maximum effectiveness.
Inspect the arrestor regularly for signs of corrosion or physical damage. Keep connectors clean and tight to maintain signal quality and protection.
Frequently Asked Questions
Does an antenna lightning arrestor work for mobile setups?
Yes, many arrestors are designed for mobile use. Ensure the unit is weather-resistant and can mount securely on your vehicle. Check the connector type matches your mobile antenna setup.
Do I need a ground wire for every arrestor?
Yes, a ground wire is critical for every arrestor to function. Without grounding, surges cannot be safely diverted. Always follow local electrical codes when installing grounding wires.
