Buying Guide – How to Choose the Best Antenna Lightning Arrestor
Selecting the right antenna lightning arrestor requires understanding your equipment and environment. This guide highlights key factors to ensure you choose a protector that fits your system and offers reliable safety.
Impedance Matching
Ensure the arrestor matches your system impedance which is typically 50 ohm for radios or 75 ohm for TV. Mismatched impedance can cause signal loss or reflection issues that affect performance.
Always check your system specs and match the arrestor impedance to avoid degradation of your signal strength.
Connector Types
Choose the correct connectors for your cables such as PL259 for ham radios or F Type for TV. A mismatch here can prevent proper installation and require adapters that may introduce weak points.
Match the connectors on both sides of the arrestor to your existing feedline for easy installation.
Frequency Range
Verify that the arrestor covers the frequency range you use especially for broadband devices like WiFi or cellular modems. Some units are limited to lower frequencies which may not suit modern setups.
Look for wideband models like 6 GHz capable units if you are protecting multiple devices on different frequencies.
Insertion Loss
Low insertion loss is vital to maintain signal strength. Look for specs under 0.5 dB to ensure minimal attenuation of your transmitted or received signals.
Prioritize models with low loss ratings to keep your connection strong and efficient.
Surge Capacity
Higher impulse wave discharge capacity means better protection against strong surges. Units rated for thousands of amps provide more safety during severe weather events.
Select models with high capacity ratings like 6000 Amps if you are in a high risk lightning zone.
Build Quality
Outdoor rated construction ensures durability against weather. Look for brass or nickel plated bodies that resist corrosion over time.
Choose durable materials to ensure long term reliability in all weather conditions.
Grounding Method
Proper grounding is essential for the arrestor to work. Ensure the unit has a ground lug or screw and that you can run a ground wire to a proper earth ground.
Plan for grounding before installation to ensure safety and functionality of the device.
Replaceable Parts
Models with replaceable discharge tubes offer longer life. If the unit takes a hit you can replace the element without buying a new arrestor.
Opt for units with replaceable parts to reduce long term costs and maintenance.
How to Use and Care for Your Antenna Lightning Arrestor
Install the arrestor as close as possible to the point where the antenna cable enters your building or equipment. This ensures that any surges are diverted to ground before reaching your sensitive radio or modem.
Connect the ground wire securely to the ground lug on the arrestor and run it to a dedicated grounding rod or electrical system ground. Avoid long ground wires which can reduce effectiveness.
Regularly inspect the arrestor for signs of corrosion or damage especially after storms. Replace the unit if you see any physical wear or if it fails to protect your equipment.
Frequently Asked Questions
Does a lightning arrestor guarantee protection from direct strikes?
No lightning arrestor provides no guarantee against direct strikes but it diverts surges from indirect strikes. It works by shunting high voltage energy to ground to reduce risk to equipment.
Do I need a separate ground cable for the arrestor?
Yes most arrestors require a separate ground cable to connect to earth ground. Check the product specs but typically a ground wire is not included so ensure you have one available.
Can I use a 50 ohm arrestor for a 75 ohm TV system?
No you should not mix impedances. A 50 ohm arrestor on a 75 ohm system can cause signal reflection and loss. Always match the arrestor impedance to your system specs.
How do I know if my arrestor is working after a storm?
Inspect it for physical damage or burns. Some models have indicator lights but many do not so visually check the connectors and casing. If unsure replace the unit for safety.
What is the typical lifespan of a lightning arrestor?
It depends on usage and weather exposure but typically years. Replace if damaged or if you suspect it has absorbed multiple strikes. Some units have replaceable parts to extend life.
Do arrestors affect my internet or signal speed?
High quality arrestors have low insertion loss which minimizes speed impact. Look for specs under 0.5 dB to ensure your signal strength remains strong and stable.
Final Thoughts on Choosing the Best Antenna Lightning Arrestor
The top picks including the Proxicast ProGrade and RAIGEN models offer reliable protection across various setups. Each model balances performance and features to suit different user needs and budgets.
Prioritize impedance matching and grounding when selecting a unit. These factors ensure the arrestor functions as intended to keep your equipment safe from electrical surges.
Remember that prices and availability may change. Verify current details and reviews before purchasing to ensure you get the best value for your protection needs.
