Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right arrester involves matching connectors checking impedance and verifying surge capacity for your setup.
Connector Type Compatibility
Ensure the arrestor matches your coax connectors such as PL-259 SO-239 or N-Type. Mismatched connectors can lead to signal loss and insecure connections.
Always verify the connector type before purchase to avoid needing extra adapters.
Impedance Matching
Most antenna systems use 50 Ohm impedance but TV and satellite setups often use 75 Ohm. Using the wrong impedance can cause significant signal reflection.
Check your system impedance to match the arrestor specification perfectly.
Frequency Range
Modern setups often involve high frequency signals like 5G or WiFi which require wide bandwidth protection. Older models might only support lower frequency HF or VHF bands.
Choose a model that covers the full frequency range of your devices.
Surge Discharge Capacity
The impulse discharge capacity indicates how much energy the unit can safely divert. Higher Amp ratings offer better protection against direct lightning strikes.
Look for a unit with a high discharge rating for maximum safety.
Insertion Loss
Insertion loss measures how much signal strength the arrestor blocks during normal operation. Lower loss is critical for maintaining strong data or voice signals.
Prioritize models with low dB loss to protect signal integrity.
Grounding Requirements
All arrestors need a proper ground connection to work effectively. Without it the surge has nowhere to divert and will damage your equipment.
Ensure you have access to a ground rod or bond point before buying.
Weather Resistance
Outdoor units should be built with materials that resist corrosion and moisture. Look for units with sealed enclosures or weatherproof ratings.
A weather-resistant build ensures longevity in outdoor installations.
Replaceable Components
Some advanced models offer replaceable gas discharge tubes that extend the device life. This can be a cost saving feature over long term usage.
Consider if the model allows for element replacement.
How to Use and Care for Your Antenna Lightning Arrestor
Connect the arrestor in line between your outdoor antenna and indoor receiver to ensure all signal passes through the protection.
Attach a grounding wire securely to the ground lug on the unit and run it directly to a cold water pipe or ground rod.
Periodically check the unit for signs of corrosion or loose connections especially after severe weather events.
Frequently Asked Questions
How does a lightning arrestor protect my radio?
It acts as a low impedance path to ground during a voltage surge. When lightning strikes it diverts the high voltage energy away from your sensitive electronics.
Do I need to replace the arrestor after a strike?
Some units are designed to handle multiple strikes but others may be compromised after a single event. Check the manufacturer details on replaceable elements for specifics.
Can I use this for my WiFi antenna?
Yes but you must ensure the arrestor supports the frequency range of your WiFi antenna. Look for models covering 2.4GHz or 5GHz bands specifically.
What happens if I don't ground the arrestor?
Without a ground connection the arrestor cannot divert the surge energy effectively. This means the surge will travel into your equipment causing damage anyway.
Do these units block the signal?
No high quality arrestors are designed to have minimal insertion loss. They should not noticeably degrade your signal strength during normal operation.
Which connectors are most common?
UHF PL-259 and SO-239 are common for ham radio. N-Type is standard for high frequency. F-Type is used for TV and cable systems.
