The Diamond D-130J Super Discone Antenna is the first ultra-wideband antenna in the market which can cover amateur radio, air traffic control and other various utility frequency bands and, in addition, even some amateur radio frequency bands within the covering frequency range can be transmitted with this antenna alone.
The D-130J is designed to be able to assemble very easily and can be built in a couple of hours by beginners. Rust free stainless steel is employed in major component parts to make the antenna rust resistant and durable. It's compact and lightweight design enables it to be installed in a wide range of environments.
Due to the high bandwidth capabilities, this antenna makes for an excellent home scanner antenna. The coax terminates in a UHF (aka PL-259) connection, so you would need to use an adapter with this antenna for most scanners.
