Vertical antenna for hand held radio

摘要

The supporting rod (1) has a terminal part (2), with metallisation (4) on the front side, and has the input end of the helix wire (3) soldered to the metallised region. On the track of the rod, the terminal part is also metallised (5), and the electrode of the condenser (6) is soldered to this. The other capacitor electrode is connected to the soldered junction (7) with the helix wire. This connection can be a metallised area (8). The terminal part (4) is made with a bored insert (9) for connecting the antenna with the input/output of the radio telephone. The terminal part or metallisation (5) is also connected in the same way, this being the electrically cold end. This antenna is directed in the horizontal direction.
