As is known, the traditional mobile phone antenna can be divided into two types according to the location of the antenna, the external antenna and the built-in antenna. Xiaobian will share with you the simple production process of external antennas in this article.
       1. 5020mm off the line according to customer requirements; (use your RG174 cable)
       2. One open wire 10mm is ready to weld SMA, the other one is open 5mm, ready to solder PCB; (use your gold-plated SMA)
       3, set of plastic sheath, welded SMA; (use your plastic sheath)
       4, soldering PCB;
       5, attach the antenna, solder the antenna core;
       6. Welding shield; (using the shield of the marine antenna, give the sample)
       7, test comprehensive characteristics;
       8, plastic enclosure;
       9. Test the finished product;
       10, the upper magnet, posted label;
       11. Put small plastic bags, small cartons, and boxes;
       In most cases, the external antenna should be clearer than the built-in signal. In the early days, the GPS handheld used an externally-turned antenna. At this time, the antenna was basically isolated from the whole machine, and EMI hardly affected it. it is good.
