By BG8GVJ Outdoor HF Amateur Radio Antenna indoor balcony For Xiegu G90 Q900. Shortwave balcony portable GP antenna. Frequency: 14-21Mhz natural resonance 3.Standing wave: less than 1.5 4. Applicable environment: balcony, outdoor (portable erection, not suitable for permanent erection) Extended scene: 1. 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. Length of antenna element length: 560CM 3. Antenna stretched length: 648CM 4. Net weight: 1.05KG 5.The actual weight of packaging and transportation (calculated volume): 3KG The complete antenna includes: Tie rod body X1 Extension rod X1 Feeder ground grid seat X1 Ground network X4 Manual X1 Resonance matching length:? The 14Mhz rod stays for 2.5-3 knots and does not pull out of the network disk.
The 18Mhz tie rod is left for 6 knots and does not extend out of the network disk. Leave the 21Mhz tie rod for 7-8 knots and not pull it out of the network disk. 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.
