New technology uses dual gate MOSFET and a gigahertz bandwidth buffer.
MFJ invented the tunable active antenna! Numerous copies have been made without success -- including most recent ones. Why? Because MFJ has made continuous improvements where others have not. The MFJ-1020C has been completely redesigned with new technology.
The dual gate MOSFET and gigahertz bandwidth buffer improve gain and selectivity, reduce noise and intermod, and are NOT prone to self-oscillations that can severely damage your receiver.
