Product Dimensions

Description

The JJB Series packs near the performance of a

conventional monopole into an incredibly compact

quarter-inch (7mm) diameter package. These

antennas are ideal for any OEM application requiring

a compact, cosmetically-attractive, low-cost antenna

solution. The antenna features a through-hole feedline

that can attach directly to a user’s PCB. Internal or

external mounting is possible.
