Automatic Magnetic Antenna Tuner - A Magnetic Loop Antenna is a resonant circuit employing a large inductor and adjustable capacitor. Efficiency depends on the inductor's size relative to wavelength. A Magnetic Loop Controller adjusts antenna tuning in real-time, syncing with Transceiver VFO movements. It communicates with various radios, enabling seamless tuning. Stepper motor resolution ensures accurate capacitor positioning, crucial for antenna performance. The Controller's firmware offers diverse functionality, enhancing user experience and antenna efficiency.

miniVNA PRO Modifications - The mini Radio Solutions miniVNA PRO is the only affordable vector network analyser (VNA) I know of that offers remote wireless operation. This is very interesting because it allows to measure the input impedance of HF antennas installed at height without having to deal with coax cable lengths, baluns nor common mode suppression chokes. However, to render the miniVNA PRO truly field proof, it requires a number of significant modifications.
