Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Choosing the right arrester depends on matching specs to your system. Here are key factors to evaluate before purchasing.
Connector Type
Ensure the arrester connectors match your antenna cables. Common types include UHF SO-239, N-Type, and PL-259.
Mismatched connectors require adapters which may degrade signal performance.
Impedance Matching
Most radios use 50 Ohm impedance while TV uses 75 Ohm. Select an arrester with matching impedance to avoid reflections.
Mismatches can cause signal loss and potential equipment damage.
Frequency Range
Check the bandwidth coverage to ensure your frequency band is supported. Most models cover DC to several GHz.
Limited bandwidth may not protect newer WiFi or cellular devices effectively.
Insertion Loss
Look for low insertion loss to maintain signal strength. Values under 0.5 dB are generally ideal for clear transmission.
Higher loss reduces effective range and audio quality.
Grounding Requirements
Every arrestor needs a proper ground path. Verify if grounding hardware is included or must be purchased separately.
Adequate grounding is essential for diverting surges safely.
Build Quality
Outdoor models should have weather-resistant coatings like nickel plating. Brass bodies provide durability against corrosion.
Cheaper units may degrade faster when exposed to moisture.
Power Handling
High-power transceivers require arresters that can handle wattage without arcing. Check power ratings like 200W.
Exceeding power limits can render the device ineffective.
Surge Capacity
Impulse wave discharge capacity indicates how much energy it can shunt. Higher amperage ratings offer better protection.
Multi-strike capability ensures continued use after smaller events.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrester as close as possible to the radio equipment inside your building. This minimizes the length of unprotected cable entering the system.
Ensure a solid ground connection using heavy gauge wire. Attach the ground lug securely to your building ground system to divert energy safely.
Inspect connections periodically for corrosion or loose fittings. Replace the unit if you suspect internal damage or repeated exposure to strong surges.
Frequently Asked Questions
Do all antenna arrestors need a ground cable?
Yes, most coaxial arrestors require a separate ground cable to divert surges safely. Check the product details to see if grounding hardware is included.
Can I use an arrestor with any radio frequency?
Not all arrestors support all frequencies. Verify that the device covers your specific frequency range like 500MHz or 6 GHz.
What happens if the arrestor gets damaged?
If the gas tube fails, protection is lost. Some models feature replaceable elements so you can upgrade without buying a whole new unit.
Will this affect my radio signal quality?
Quality arrestors have low insertion loss and should not noticeably affect signal. Poor units might introduce attenuation or noise.
How often should I replace the arrester?
Ideally check annually for wear. Replace immediately after a major lightning strike even if the unit looks intact.
Is an arrestor different from a surge protector?
Arrestors divert high voltage lightning energy to ground whereas general surge protectors filter smaller transients. Arrestors are for outdoor antenna feeds.
Can I use it indoors only?
Outdoor rated models handle weather better. If installed indoors ensure the cable path is protected from moisture and temperature extremes.
Does it block DC power for active antennas?
Many models support DC pass-through for active antennas. Confirm the specs if you are using powered masts or preamps.
