Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right arrestor depends on matching its specs to your gear type and environment.
Connector Type Compatibility
Ensure the arrestor uses the same connectors as your antennas such as N-Type PL-259 or F-Type to avoid adapters. Mismatched connectors can introduce signal loss and mechanical stress.
Always check both ends of the unit to match your existing coax cables exactly.
Impedance Matching
Arrestors come in 50 Ohm for radio gear and 75 Ohm for TV and satellite. Using the wrong impedance causes signal reflection and weakens reception.
Match the Ohm value to your system for best signal integrity and equipment protection.
Frequency Range
Check the arrestor covers your signal frequencies. Cellular boosters need wide ranges up to 6 GHz while CB and Ham often stay below 1 GHz.
Choose a model that spans your lowest to highest operating frequencies for full protection.
Insertion Loss
Lower insertion loss keeps your signal strong and clear. Look for values under 0.5 dB to prevent noticeable degradation in audio or data quality.
Prioritize models with ultra-low loss for sensitive receivers and boosters.
Surge Capacity
Higher discharge capacity means better handling of strong lightning surges. Units rated for thousands of Amps and V offer more safety than basic models.
Select higher capacity units for areas with frequent thunderstorms.
Build Materials
Outdoor units must resist corrosion and weather. Brass nickel plating and PTFE insulation ensure longevity in harsh conditions.
Avoid cheap metals that degrade quickly to maintain protection over time.
Grounding Requirements
Effective arrestors need a dedicated ground cable to divert surges. Confirm if the model includes a ground lug or cable to avoid extra costs.
Always connect directly to your earth ground for maximum safety.
Installation Flexibility
Bulkhead mountable options allow direct mounting through panels. This is ideal for indoor setups where cables enter through walls.
Choose flexible mounting to simplify wiring and keep your setup tidy.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor as close as possible to where the antenna cable enters your building. This placement ensures surges are diverted to ground before they reach your radio or modem.
Connect the ground wire securely to a proper earth ground rod. A poor ground connection renders the arrestor useless and may lead to equipment damage.
Inspect the unit yearly for signs of corrosion or damage. If you live in a storm-prone area replace the discharge tube or entire unit after a major thunderstorm.
Frequently Asked Questions
Does an antenna lightning arrestor prevent all lightning damage?
An arrestor significantly reduces risk by diverting most surge energy to ground. However no device guarantees 100% protection against direct hits. Using proper grounding adds an extra layer of safety for your equipment.
Do I need to ground my arrestor?
Yes grounding is essential for the arrestor to work. Without a connection to earth ground the surge has nowhere to go and will travel to your radio. Always use a dedicated ground wire.
Can I use a 75 Ohm arrestor for my CB radio?
No 75 Ohm arrestors are for TV and satellite. Using one on your 50 Ohm CB setup causes signal reflection. Always match the Ohm value to your radio gear exactly.
How often should I replace my arrestor?
Inspect annually and replace after a major lightning strike. Some models have replaceable discharge tubes that you can swap without replacing the whole unit for cost savings.
Will an arrestor affect my signal strength?
A quality arrestor adds minimal loss usually under 0.5 dB. This slight reduction is not noticeable in most setups. Look for low loss specs to keep your signals clear.
Can I install an arrestor indoors?
Yes you can install indoors but it is best to place it where the cable enters the house. This ensures surges are stopped outside the living space.
What if my arrestor has female connectors?
You may need adapters to connect to male-ended cables. Ensure adapters are also rated for your frequency and impedance to avoid signal loss.
Do I need a separate ground cable?
Most arrestors do not include a ground cable so you must buy one separately. Check product details carefully to confirm what is included with your unit.
Final Thoughts on Choosing the Best Antenna Lightning Arrestor
Choosing the right lightning arrestor depends on matching connector types, impedance, and frequency range to your specific setup. The RAIGEN model leads overall for versatility while the Workman A28 offers the best budget option.
Prioritize low insertion loss and proper grounding for the safest and most effective protection. A quality arrester can save you costly repairs by diverting dangerous energy safely to the earth.
Always double-check current availability and listings before buying since features and stock change frequently. Invest in a proven model that fits your environment for peace of mind during storm season.
