ABSTRACT:
An antenna device includes an antenna housing having a chamber and a slot formed in one end and formed between two arms and communicating with the chamber, an antenna member having a stud engaged into the slot and rotatably coupled to the antenna housing with a pivot axle and having two or more flat surfaces formed in the stud. A spring-biased follower is slidably received in the antenna housing and includes an actuator for engaging with either of the flat surfaces of the antenna member and for anchoring and retaining the antenna member to the antenna housing at selected angular positions. The antenna device includes a greatly simplified structure with a greatly reduced expense.
