Mini whip active antenna VLF, LW, SW, HF for RTL SDR, Degen, Tecsun, Sony
Fully Balance Active antenna (dipole) work from 50 kHz to 45 Mhz with gain 16 dbi. Fully balanced tecnology can stop receiving interference via coaxial cable and receiver body. Forget about ferrite rings on coaxial cable! Also reduceing synphase interference over 60 db help ignore local home interference. Now i can connect my Degen 1103 to laptop via linear input for receiving and decoding digital transmission. Individual tuning and checked - pair input tranzistor BF862 individually sorted. Antenna input have 3 stage protection from electrostatic discharge. Power input have 2 stage protection from change polarity power and overvoltage (each one in antenna, second in power injector). Low noise stabilise power injector can use with swithing power adapter (but linear adapter better). External power voltage from 5 to 12 volt, current 0.1 ampere.
It is not simple and not cheap, but it is right antenna. The author of the scheme Mr. Active antenna unit (fully assembled and tested PCB). Power injector unit (fully assembled and tested PCB). You need for use NOT included!
2 antenna element 0.3 meter each (you can increace lenght for better sensivity). The best result with metall disk, dish or can 15-35 cm. Diameter (as on the photo above). Coaxial cable with SMA connector (between antenna and injector). Coaxial cable with SMA connector (between receiver and injector).JST type, Arduino like, or other with step 2.54 mm.
