Use Q900, G90S with built-in antenna or other high-performance antenna can work in 7M-51M 2. The natural resonance can work at around 430Mhz standing wave 2 in the 14M state. The SDR receiver is used in all sections Separate the length of the three main parts: 1. Extension pole 57cm, antenna rod body 63.5cm, feeder and ground grid base 22cm 2.

Cooperate with the high performance of the sky: the lever is fully extended, the ground net is fully straightened. Natural resonance is a quarter of a wavelength, 14M leaves 2.5M to 3M without pulling. 21MHz natural resonance, the tie rod is left with 7 to 8 sections. 14MHz natural resonance, the ground network is the same as the picture, do not lengthen; other bands remain unchanged, only shorten the rod.
Use Q900 antenna G90S antenna or other high-performance antenna to extend the ground network and pull out all the antennas. 4 cable ground cables, each cable has 16 ground cables, a total of 64 ground cables.
