Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right arrestor requires considering several factors to ensure your equipment receives adequate protection.
Connector Type Compatibility
Your arrestor must match the connectors on your antenna and radio such as UHF SO-239 N-type or F-type. Using mismatched connectors can introduce impedance mismatches that degrade signal quality or require extra adapters that add failure points.
Always verify the connector gender and type before purchasing to ensure a direct fit for your system setup.
Frequency Range Support
Different arrestors support different frequency ranges from HF to 6 GHz. Ensure the unit covers the frequencies used by your radios or cellular modems to avoid signal loss or ineffective protection.
Check the specs to confirm the device handles the specific bands of your equipment for optimal performance.
Impedance Matching
Impedance mismatch between the arrestor and your coaxial cable can cause signal reflections and attenuation. Most ham radio systems use 50 Ohm lines while cable TV systems use 75 Ohm lines.
Choose an arrestor with matching impedance to prevent signal degradation and ensure efficient power transfer.
Insertion Loss
Insertion loss refers to the signal power lost as it passes through the arrestor. Lower is better typically below 0.5 dB to maintain strong signal strength for your transmissions.
Look for products advertising very low insertion loss to ensure your signal quality remains high.
Voltage Discharge Rating
Gas discharge tubes inside the arrestor have voltage ratings such as 90V or 230V. Higher ratings may handle more energy but can slightly delay response time to smaller surges.
Select a rating that balances sensitivity and robustness for your specific environment and equipment sensitivity.
Ground Connection Requirements
Proper grounding is essential for the arrestor to divert surges effectively. Most units require a dedicated ground cable to connect to a grounding rod or building ground system.
Ensure you have access to a suitable ground point and purchase a ground cable if not included.
Outdoor Durability
Since arrestors are often mounted outside the weather resistance of the housing matters. Look for brass or nickel plated bodies that resist corrosion in rain and humidity.
Choose units rated for outdoor use to ensure they last long enough to protect your investment.
Power Handling Capacity
Some arrestors are rated for specific power levels like 200W. High power transmitters need units that can handle the heat and stress without melting or failing.
Check the power rating if you transmit high wattage to avoid damaging the arrestor during normal operation.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor as close as possible to the point where the coaxial cable enters your building. This placement ensures that any surge induced on the cable line grounded before it reaches your sensitive electronics.
Connect the grounding terminal on the arrestor to a proper earth ground using a heavy gauge wire. A poor ground connection can render the arrestor ineffective leaving your equipment vulnerable to damage during storms.
Inspect the arrestor periodically for signs of corrosion or physical damage especially if mounted outdoors. While durable these components should be checked annually to ensure the internal gas discharge tube remains functional.
Frequently Asked Questions
Do I need a grounding cable for the arrestor to work?
Yes a grounding cable is required for the arrestor to function correctly. The device works by diverting surge energy to the earth ground so without a proper ground connection the energy cannot be safely dissipated.
Can I use a 50 Ohm arrestor on a 75 Ohm system?
It is not recommended to mix different impedances as it causes signal loss and reflection. Use an arrestor that matches your system impedance such as 50 Ohm for radios or 75 Ohm for TV.
Does a lightning arrestor prevent all lightning damage?
An arrestor protects against surges traveling along the feedline but not direct strikes or induced damage from nearby events. It significantly reduces risk but no device can guarantee total protection against all lightning scenarios.
What is insertion loss and does it matter?
Insertion loss measures how much signal power is lost passing through the arrestor. Low loss matters because high values can weaken your signal strength reducing communication range and clarity on your radio.
How often should I replace my lightning arrestor?
Some units have replaceable gas tubes while others do not. If your unit has suffered a major surge event replace the element or unit immediately. Otherwise a visual inspection every year usually suffices.
Can I install an arrestor inside the house?
Ideally the arrestor should be mounted outside before the cable enters the building. Indoor installation leaves your entry point unprotected allowing surges to enter the home before being diverted to ground.
Does the arrestor affect my data speeds?
A quality arrestor with low insertion loss will not noticeably affect data speeds. However cheap units with poor construction might introduce interference that slows down your connection slightly.
