Since 2014, new TVs have been equipped with DTMB functions. The popular point is that newly-listed TVs support the free reception of TV towers' digital signals through an antenna. Speaking from Xiaobian, Xiaobian is located in Shenzhen. , Can receive local television stations in Shenzhen and adjacent to Hong Kong television (TVB Jade Tailuo, is not it envy jealousy!) A total of 40 + sets, and most are high-definition, based on such a good resource we certainly can not let go! Today Xiao Bian gave everyone a set of simple DIY ground-based high-definition (DTMB) antenna production methods. The cost is low and the effect is significant. We might as well try it!
Material: 2 meters long 2.5-4mm single core copper wire, video cable, TV TV male, insulating tape
In the first step, the 2-meter-long 2.5-4mm single-core copper core wire is first stripped of the plastic skin, and the bare copper core wire helps to improve the television signal reception performance.
The second step, the stripped copper core wire according to Figure 1 fold shape, note that A, B can not be shorted two points, insulated by insulating tape, the actual effect shown in Figure 2.

In the third step, connect the video cable to the diamond antenna. The connection method is as shown in Figure 2. The other end is connected to the TV TV male and inserted into the antenna interface of the TV (the TV antenna interface is the TV female).
The fourth step is to turn on the DTV or DTMB function of the TV and perform the tuning (which can also be automatically adjusted manually). If the signal is not good, the placement of the diamond antenna can be properly adjusted.
