Ordering Information
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.
* Requires proximity ground plane
