Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right protector requires understanding your setup and local weather risks. Here are the main factors to consider when making your decision.
Connector Type
Ensure the arrestor matches your coaxial cable connectors. Common types include PL-259 SO-239 N-Type and F-Type. Mismatched connectors can cause signal loss or damage.
Always verify the gender and impedance of your connectors before purchasing.
Impedance Matching
The device must match the impedance of your system such as 50 Ohm or 75 Ohm. Mismatches can lead to reflections and degraded performance.
Check product specs to confirm the impedance value aligns with your equipment.
Frequency Range
Select an arrestor that covers the frequencies your antenna uses. Some units support DC to 6GHz for cellular while others focus on VHF.
Verify the frequency range to ensure your signal remains unobstructed.
Insertion Loss
Lower insertion loss values mean better signal transmission. Look for values below 0.5 dB for optimal performance.
Prioritize low loss to maintain strong signal strength.
Impulse Capacity
Higher discharge capacity allows the unit to handle stronger surges. Look for units with multi-strike capability for durability.
Choose a unit with a high amp rating for better safety.
Material Quality
Durable materials like brass and nickel plating resist corrosion. Weather-resistant housing ensures longevity outdoors.
Opt for robust materials to avoid premature failure.
Grounding Requirements
Most arrestors need a proper ground connection to divert surges. Ensure you have a path to earth ground.
Always connect the grounding terminal properly for safety.
Budget
Prices vary based on brand and features. Decide how much protection you need versus how much you want to spend.
Balance cost with the value of your equipment.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor between the antenna coax and your radio equipment. Place it as close to the entry point of the building as possible.
Connect the grounding lug to a cold water pipe or dedicated ground rod. Use a thick wire for the ground path to ensure low resistance.
Regularly inspect the unit for signs of wear or corrosion. Ensure all connections remain tight and secure over time.
Frequently Asked Questions
Do antenna lightning arrestors actually stop damage?
Yes they divert high voltage surges away from sensitive gear. They protect your receiver from burning out during storms.
Does a lightning arrestor affect signal quality?
Quality units have low insertion loss so impact is minimal. High loss units can degrade your signal strength.
Do I need to replace the arrestor after a strike?
Some units have replaceable tubes while others do not. Check if your model has a replaceable element for reuse.
Can I use a UHF arrestor for a 5G signal?
UHF arrestors typically cover lower frequencies. For 5G use a wideband N-Type model rated to 6GHz.
Where should I install the ground connection?
Connect it to a dedicated ground rod or metal pipe. The connection should be as short and direct as possible.
Is a lightning arrestor required for mobile antennas?
It is highly recommended to prevent vehicle electronics damage. Even a small ground connection helps reduce risks.
Final Thoughts on Choosing the Best Antenna Lightning Arrestor
The Proxicast and Diamond models offer top-tier protection for different needs. Whether you need UHF or N-Type there is a fit for every setup.
