Impedance
Most radio systems use 50 ohm impedance but TV uses 75 ohm. Mismatched impedance causes signal loss. Verify the ohm rating matches your gear.
Ensure ohm rating matches your system.
Surge Capacity
Surge capacity determines how much energy it handles. Higher amp ratings offer better protection. Look for gas discharge tubes with multi-strike capability.
Higher amp ratings offer better protection.
Insertion Loss
Insertion loss reduces signal strength. Good arrestors have very low loss under 0.5 dB. Check specs to ensure minimal signal degradation.
Look for minimal signal loss.
Build Quality
Outdoor arrestors need weather-resistant materials. Brass nickel plating and PTFE insulation help prevent corrosion. Ensure it is rated for outdoor use.
Ensure outdoor weather resistance.
Grounding Options
All arrestors need grounding to work. Some include ground lugs or screws while others do not. Verify what is included to plan your wiring.
Check if ground wire is included.
Replaceable Parts

Frequently Asked Questions
Does an antenna lightning arrestor guarantee equipment safety?
An arrestor reduces risk but cannot guarantee complete safety. It diverts most surges to ground. For best protection use it with proper grounding and surge protectors.
Can I use an arrestor indoors?
You can install arrestors indoors near the entry point. However outdoor rated models are recommended for longevity. Keep them away from moisture and heat sources.
How do I ground an antenna lightning arrestor?
Connect a copper ground wire from the arrestor lug to your grounding rod or building ground. Ensure a solid metal-to-metal connection for effective diversion.
Will an arrestor affect my signal quality?
A quality arrestor adds minimal insertion loss. Good models keep loss under 0.5 dB. This is usually imperceptible to standard radio setups.
Do I need a separate ground wire?
Most arrestors require a separate ground wire. The unit diverts surges to ground. Ensure you buy the wire if not included.
What happens if my arrestor survives a strike?
If it has multi-strike capability it may still work. However inspect it after every strike. Replace if the gas tube shows signs of failure.
