Ironman High Performance Antenna Upgrade
$ $35.00

Our top-performing antenna, the IronMan, ensures superior signal quality. It's sturdy, reliable, magnetic, and ideal for Simtek StealthALERT. Includes a convenient 3m cable for easy installation. Ideal for heavy-duty safes, off-grid solutions, construction sites, and any scenario requiring top-tier reliability.

• Heavy-duty antenna
• Made out of copper for superior signal stability & performance
• 3M long cable (~10 feet length)
• Cable diameter 5mm  
• 2.5" diameter magnetic base, super strong 

Gain: 6dBi

Frequency: 698 - 960; 1710 - 2700Mhz 

Cable Length: 3 meters (9.8ft) 

Note: If you plan to string the antenna outside of your safe, you will likely need to add the braided metal extension cable. The ironman antenna cable thickness is 5mm, making it too large for most safe holes, however it will fit perfectly when daisy-chained with the braided metal extension cable. If you keep the ironman antenna inside the safe walls, you don't need to worry about the cable thickness.
