**Note Test Parameter: MIL-STD 220 50 Ohm Insertion Loss Test Methodology. Test was performed on a single device with 6-inch leads.

***Note dBµV (using the Greek letter µ ["mu"] instead of u) is voltage expressed in dB above one microvolt into a s pecific load impedance; in land mobile and broadcast this is commonly 50 ohms.

****Note dBu is E (electric field intensity) expressed always in decibels above one microvolt/meter (dBµV/m)---dBm is a power level expressed in dB above one milliwatt

Stedi-Power Inc. is the manufacturer of Stedi-Power Surge Arresters and Transient Voltage Surge Suppressors.  Surge suppressors are also known as surge protectors, surge protective devices, surge protection devices, or SPD.  Surge Arresters are sometimes referred to as Secondary Surge Arresters, or SSA.  Stedi-Power is one of a very small number of manufacturers of dual rated surge suppressors.  All of our equipment is qualified as both surge arresters and surge suppressors.
