PY1AHD Handheld Magnetic Loop Controller for a HF Light Backpack Magnetic Loop Antenna



You can see on this video my new created device after four years work in designing several remote control systems to tune the variable capacitor of a Small Magnetic Loop Antenna.
The antenna can be carried on my back, with a light and simple Back Support described on my web page, or I can temporarily fix the antenna on a balcony or window adjusting the antenna's resonating frequency from a distant place.

Hello Alex, This is a very interesting devise. Can you expand on the motor
control, is it homemade or a ready made product and how is the control
connected to the motor? Thanks in advance. Dave K2ZU

Author gmcjetpilot (5 years)
I would also like to see the schematics, parts list and more detail how to
make this remote control tuner. It is a servo I see and some kind of RF
transmitter to control the servo like a RC model, but what parts did you
use and any details to duplicate would be nice. Thanks I need something
just like this.

Alex, notei que o capacitor que você está usando no teu projeto é similar
ao que penso em comprar para um projeto de tuner automático de antena, mas
o vendedor não soube informar a voltagem máxima suportada. Fiquei
preocupado com a aparente proximidade das placas. O meu rádio é um Yaesu
FT857-D, que gera até 100W na saída em HF. Você saberia informar qual seria
a voltagem máxima para esse capacitor? Seguem algumas fotos:
