Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Choosing the right lightning arrestor requires careful consideration of your specific equipment and installation environment.
Connector Type
Ensure the arrestor connectors match your antenna and radio cables. Common types include UHF SO-239 PL-259 N-Type and F-Type. Mismatched connectors will require adapters which can degrade signal quality.
Always verify the connector type before purchasing to ensure a direct fit.
Impedance Match
Most radio systems use 50 Ohm impedance while TV and satellite use 75 Ohm. Using a mismatched arrestor can cause signal reflections and damage your equipment. Always check the Ohm rating on the device.
Select a 50 Ohm arrestor for radio and 75 Ohm for TV systems.
Frequency Range
Different arrestors support different frequency ranges. Some cover DC to 500MHz for HF/VHF while others cover up to 6GHz for cellular and WiFi. Ensure the range matches your signal frequency.
Verify the supported frequency range covers your operating band.
Surge Capacity
Higher surge capacity means better protection against strong strikes. Look for discharge ratings and multi-strike capability. Professional units often have higher amp ratings for better safety.
Prioritize higher discharge ratings for critical equipment.
Insertion Loss
Low insertion loss ensures signal strength is maintained. High loss arrestors can weaken your signal. Look for units with less than 1dB loss for best results.
Choose arrestors with minimal insertion loss to maintain signal quality.
Build Quality
Outdoor arrestors must withstand weather. Look for brass or nickel plated bodies and weatherproof ratings. Durability ensures long-term performance without rust.
Opt for corrosion-resistant materials for outdoor installations.
Grounding Requirements
Proper grounding is essential for arrestors to work. Ensure you have a grounding wire available. Some units include ground lugs while others do not.
Plan for proper grounding infrastructure before installation.
Budget
Prices vary from budget to premium. While expensive units offer better specs often the middle range offers good value. Choose based on your risk tolerance.
Balance features with cost to find the best value.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor between your antenna coaxial cable and your radio or modem. Ensure it is mounted securely and close to the entry point of the building.
Connect the ground lug or screw to a proper earth ground system using a copper grounding wire. This path is essential for diverting surges safely away from equipment.
Regularly inspect the unit for signs of corrosion or damage especially after storms. Check connections to ensure they remain tight and clean for optimal performance.
Frequently Asked Questions
Do lightning arrestors really work?
Yes lightning arrestors work by diverting dangerous electrical surges to ground before they reach your sensitive equipment. They use gas discharge tubes to shunt excess voltage away effectively protecting radios and modems from damage during storms.
Where should I install the arrestor?
Install the arrestor as close as possible to the point where the coaxial cable enters your building. This location ensures the surge is diverted before it can travel along the cable and damage your internal electronic equipment.
Does an arrestor guarantee protection?
While arrestors provide excellent protection they do not guarantee immunity from direct lightning strikes. They are designed to handle indirect surges and transients. Always unplug sensitive equipment during severe storms for maximum safety.
Can I use one arrestor for different setups?
You generally need specific arrestors for specific systems. A 50 Ohm radio arrestor won't work for 75 Ohm TV setups. Ensure compatibility with your frequency and impedance to avoid signal issues.
Do I need a ground wire?
Yes every effective arrestor requires a connection to a proper earth ground. Without this path the surge cannot be diverted safely. Check the product description to see if a ground lug is included.
How do I maintain my arrestor?
Periodically check the unit for rust or physical damage. Ensure all connections remain tight and corrosion-free. If the unit shows signs of wear replace it to ensure continued protection.
