Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right lightning arrestor depends on several technical factors including connector type impedance and frequency range. This guide explains what to consider to ensure proper protection for your specific setup.
Connector Type
Ensure the arrestor matches the connectors on your antenna and radio such as N-Type SO-239 or F-Type. Mismatched connectors will require adapters that can introduce signal loss or weak points.
Choose connectors that fit your existing cabling without additional modifications for a secure reliable setup.
Impedance Matching
Most RF systems operate at 50 Ohms while TV and satellite use 75 Ohms. Select an arrestor that matches your system impedance to prevent signal reflection and degradation.
Matching impedance is vital for maintaining signal strength and equipment safety during normal operation.
Frequency Range
Confirm that the unit supports the frequencies you use. Broadband models cover from DC to six GHz while others may be limited to lower ranges for HF or VHF.
A wider frequency range ensures future proofing for new wireless technologies or added devices.
Insertion Loss
Look for models with low insertion loss typically less than 0.5 dB to ensure your signal stays strong. High loss can reduce communication range or data speeds.
Low loss designs preserve signal integrity and help maintain optimal performance across your system.
Surge Capacity
Check the discharge tube rating and impulse wave capacity to ensure it can handle expected electrical surges. Higher amp ratings offer better protection against severe strikes.
Higher surge capacity extends the lifespan of the unit during major electrical events.
Grounding Requirements
Proper grounding is essential for the arrestor to function. Ensure you have a low resistance earth ground and the required cables to connect the unit safely.
A solid grounding connection diverts harmful energy away from your electronics effectively.
Environmental Durability
Outdoor models should have weather resistant coatings like brass plating or nickel to prevent corrosion. UV stable materials ensure longevity when exposed to sun and rain.
Durable construction prevents failure due to environmental wear over time.
Replaceable Components
Units with replaceable discharge tubes offer better long term value than disposable ones. This allows you to swap the core after a surge without replacing the entire housing.
Replaceable parts reduce waste and save money on future protection needs.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor as close to the entry point of your building as possible. This ensures that any surge entering your system is diverted to ground before reaching sensitive electronics.
Connect the arrestor ground lug to a dedicated earth ground rod or building ground bus using thick copper wire. A poor ground connection can render the protection ineffective during storms.
Inspect the unit periodically for signs of corrosion or physical damage. Tighten any loose connectors and replace the discharge tube if the manufacturer indicates it has reached its limit.
Frequently Asked Questions
Do lightning arrestors work for all weather events?
Arrestors are specifically designed to divert high voltage surges caused by lightning. They offer excellent protection for electrical spikes but cannot prevent physical damage from direct strikes.
Can I use a 50 Ohm arrestor for a 75 Ohm system?
No using mismatched impedance will cause signal reflections and degradation. Always choose an arrestor with the same impedance rating as your cables and equipment.
Is grounding really necessary for an arrestor to work?
Yes grounding is essential. Without a low resistance path to earth the surge has nowhere to go and will continue through the cable to your connected devices.
How long do gas discharge tubes last?
Most tubes handle multiple strikes but may degrade after large surges. Replaceable units allow you to swap the core when capacity is reduced ensuring continued protection.
Will an arrestor affect my radio transmission?
High quality arrestors have very low insertion loss and should not affect your transmission. However poor or mismatched units can introduce signal loss or standing waves.
Do I need an arrestor if my antenna is not tall?
Yes even low antennas can attract surges from nearby strikes. An arrestor provides essential protection for all outdoor communication equipment regardless of height.
Final Thoughts on Choosing the Best Antenna Lightning Arrestor
The RAIGEN and Diamond models stand out for their broad frequency support and high quality construction making them ideal for professional setups. The N Type and Proxicast units offer great value for specific applications like CB or satellite.
Prioritize proper grounding and impedance matching to ensure your chosen model functions as intended. Investing in a reliable unit saves money by protecting expensive radios and boosters from costly damage.
