EMP Shield Radio EMP Protection Up To 500 Watts Gives Mid-Power Stations An Inline Guard Against EMP And Lightning
The EMP Shield Radio EMP Protection Up To 500 Watts is built for HF, VHF and UHF stations that need more headroom than a 200 watt protector offers. The unit connects into the coax run through an IN port and an OUT port, and a GND stud on its side takes the ground connection. EMP Shield lists radios, transceivers, base stations and antennas among the equipment it is meant to protect.
Two versions share the 500 watt rating. ANT-500-UHF carries UHF connectors in a black housing, and ANT-500-N carries N connectors in a blue housing. Ham operators, first responders and emergency communications specialists who run up to 500 watts can pick whichever connector matches the rest of their station.
EMP Shield Radio EMP Protection Up To 500 Watts Features
Protection Across All Three EMP Phases And More
EMP Shield states the unit protects against E1, E2 and E3, the three phases of an EMP. Coronal mass ejections, lightning and power surges are covered too, so one protector on the line addresses several risks to a 500 watt station.
Response In Under One Nanosecond
According to EMP Shield, the unit starts shunting over-voltage in less than one nanosecond. That quick reaction is how it keeps a surge from reaching the transceiver and other gear down the line.
Room For Stations Above 200 Watts
Once your station runs past 200 watts, the smaller model in this line no longer fits. The 500 watt rating covers those stations up to 500 watts in the same inline format.
Two Connector Styles, One Rating
Choose UHF connectors, the SO-239 style EMP Shield names for this line, or N connectors. The choice changes only the connectors, the model number on the label and the body color. Matching your current coax ends keeps the install simple.
Labeled Ports And A Dedicated Ground Stud
IN, OUT and GND are printed on the label next to each connection point. The ground stud is threaded, and the model number on the label tells you at a glance that you have the 500 watt unit.
Claims EMP Shield Reports
EMP Shield reports testing at Keystone Compliance to MIL-STD-188-125-1, MIL-STD-461G, MIL-STD-464C and RS-105, adding that Keystone Compliance does not endorse any product. The company also says it is listed by the Department of Homeland Security in its EMP resilience report. EMP Shield is a veteran-owned company that builds its products in Kansas, USA.
Real-World Applications
Ham Stations Running Up To 500 Watts. Operators whose output tops 200 watts can put this unit in the coax and stay within its rating all the way to 500 watts.
Base Stations. EMP Shield designs this line for base stations and the transceivers they use, keeping a protector on the antenna connection of a fixed station.
First Responder Radio Rooms. First responders are among the users EMP Shield names for its radio protection. A radio room running up to 500 watts can use either connector version.
Emergency Communications Teams. Emergency communications specialists who rely on their radios to stay connected during critical events can leave this protector in the line full time.
Practical Comparison
The 500 Watt Model Versus The 200 Watt Model
The two look alike and offer the same connector choices. The 200 watt unit is rated only to 200 watts, while this one reaches 500 watts. Pick the 500 watt version if your station sits anywhere between those two levels.
The 500 Watt Model Versus The 1000 Watt Model
Stations that run above 500 watts need the 1000 watt unit. If your power stays at 500 watts or less, this model covers you.
Inline Radio Protection Versus A Whole-Home Panel Unit
A whole-home panel unit protects the house wiring at the breaker panel. It doesn't sit in your coax, so it doesn't cover the antenna path into your radio. This unit protects that path, and the two can work side by side.
Buyer Guidance
Picking The Right Power Rating
Look at the full output your station can reach, including any amplifier. If that number is above 200 watts and no more than 500 watts, this is the rating to choose. Above 500 watts, move to the 1000 or 1500 watt version.
Picking The Connector And Planning The Install
Go with the UHF option for coax ending in UHF connectors and the N option for coax ending in N connectors. The unit installs inline at the IN and OUT ports with a ground at the GND stud. Use EMP Shield's installation instructions for the radio models when you set it up.
This May Be A Good Fit If
- Your station runs above 200 watts but stays at or under 500 watts
- You use UHF or N connectors on your coax
- You want a protector that stays connected while you transmit
- You operate a ham, base or emergency station
Common Questions
How Do The ANT-500-UHF And ANT-500-N Differ?
The UHF version has UHF connectors and a black housing. The N version has N connectors and a blue housing. Both carry the 500 watt rating and the same IN, OUT and GND layout.
Is The 500 Watt Unit OK For A Lower-Power Station?
Yes. EMP Shield rates it for systems up to 500 watts, so a station running less than that is within its rating.
What Is The GND Stud For?
It is the unit's labeled ground connection point. EMP Shield's instructions explain how to make the ground connection for your station.
What Is The EMP Shield Warranty?
EMP Shield covers defects in materials and workmanship for 10 years under a limited warranty, with repair or replacement. A unit destroyed by lightning is replaced for $50 once you return the destroyed unit. EMP Shield's separate protection policy may reimburse connected electronics up to $25,000 if its conditions are met.
