Balanced ATU
A balanced ATU, An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
Coupleur pour antenne Levy
As a multi-band antenna, the Levy antenna is undoubtedly the best and cheapest antennas, but its agreement requires a suitable coupler, which sometimes represents a brake to the installation
De ultieme Z-match voor HF
The reference hardware design ad prototype I built is using an Arduino Uno and has 100 watt capability
Esperimenti com l'accordatore A T
Accordatori a T e non i classici LC che differenze ci sono ?,la configurazione a T fa si che in entrata e all' uscita dell'accordatore vede anche qualche migliaio di ohm di impedenza
Een Z-match
Measuring the HF voltage is done with a simple diode detector
