Abstract: An improved monopole antenna for in-duct use is disclosed. The antenna comprises a center pin rod disposed coupled to a connector housing by a molded dielectric. The center pin rod includes a pin portion which is disposed through a portion of a connector portion of the connector housing, thereby allowing a mating RF connector to couple to the monopole antenna. The center pin rod is composed of a single assembly or a single piece of material, thereby eliminating the need to solder the antenna to a RF connector.
