Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right arrester involves checking connector types, impedance, and frequency range to match your specific radio system.
Connector Type
Ensure the arrestor matches your existing cable connectors like SO-239, N-Type, or F-Type. Mismatched connectors can lead to poor contact and signal loss.
Always verify the connector gender such as male to female to fit your inline setup correctly.
Impedance Match
Choose an arrester with the same impedance as your system, typically 50 Ohm for radios and 75 Ohm for TV. Mismatch causes reflection and signal degradation.
Matching impedance ensures efficient power transfer and protects your equipment from damage.
Frequency Range
Check the frequency limits to ensure coverage for your specific signals. A wider range like 0 to 6 GHz covers both radio and modern cellular data.
Verify that the arrestor supports your operating frequencies to maintain signal integrity.
Surge Capacity
Look for models with high impulse wave discharge capacity to withstand severe strikes. Higher Amp ratings provide more reliable protection against direct hits.
Ensure the arrestor can handle the expected surge energy for your installation.
Gas Discharge Tube
Most arrestors use gas discharge tubes to divert energy to ground. A replaceable tube allows you to reset the device after a surge event.
Check if the tube is replaceable to extend the useful life of the arrestor.
Insertion Loss
Low insertion loss is critical to prevent weakening your signal. Aim for less than 0.5 dB to maintain strong transmission and reception quality.
Select an arrestor with minimal loss to keep your signal strength consistent.
Weatherproofing
Since the arrestor is usually mounted outdoors, ensure it has weather-resistant materials. Brass plating or stainless steel helps prevent corrosion over time.
Look for ratings that confirm outdoor durability for long-term reliability.
Ground Connection
Ensure the arrestor includes a ground screw or lug for proper earthing. Without a solid ground connection, the surge protection will not function effectively.
Always use a heavy-gauge ground wire to connect the arrestor to your earth system.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor between the antenna and your equipment with the antenna side facing the outdoor cable.
Attach a ground wire to the arrestor grounding screw and run it directly to your main ground rod system.
Inspect connections periodically for corrosion and ensure the ground path remains secure for optimal protection.
Frequently Asked Questions
Do I need a lightning arrestor if my antenna is grounded?
Yes, grounding the antenna alone may not protect your equipment from surges traveling through the coax cable. An arrestor provides a direct path to divert this energy safely.
Does a lightning arrestor affect signal quality?
Most quality arrestors have very low insertion loss meaning they do not noticeably affect signal quality. However, always check specs for minimal loss values.
What is the difference between 50 Ohm and 75 Ohm arrestors?
The difference lies in the impedance matching. 50 Ohm is standard for radios while 75 Ohm is used for TV and cable. Using the wrong type causes reflection.
Do I need to replace the arrestor after a strike?
If it has a replaceable gas discharge tube, you can replace that part instead of the whole unit. Some arrestors may require replacement if the element is damaged.
Can I use an arrestor with a signal booster?
Yes, arrestors are often compatible with signal boosters but ensure they support the booster's frequency range and impedance for optimal performance.
How close to the radio should I install the arrestor?
Ideally, install the arrestor as close to the entry point of the building as possible. This minimizes the length of cable inside the home that could carry a surge.
Is an arrestor enough protection during a severe storm?
An arrestor helps divert surges but disconnecting equipment during severe storms provides the highest level of safety for valuable electronic gear.
What grounding cable should I use with the arrestor?
Use a heavy-gauge ground wire such as 10-gauge copper to connect the arrestor to your main ground. Proper wire thickness ensures low resistance to ground.
Final Thoughts on Choosing the Best Antenna Lightning Arrestor
This guide highlights top performers like the RAIGEN and Diamond Antenna models that offer reliable protection across various frequencies.
Prioritize impedance matching and connector types to ensure seamless integration into your existing antenna system.
Always check current availability and ensure you have a proper grounding path installed for maximum safety.
