Misuratore di guadagno d'antenna
Il guadagno G puo' essere ottenuto comparando il valore della max.densita' di potenza in una particolare direzione del DUT con l'analoga densita' di potenza di una antenna di riferimento

PCB Vswr bridge
When building HF/VHF equipment it is often required to add a VSWR sensing circuit into the rig

QRP Wattmeter
The PIC16C71 microprocessor offers a four input Analogue to Digital converter, which I could use to read the voltages from the sensor and enough interface pins to drive an LCD display

RF measuring bridge for the standing wave alignment
An even QRP station is dependent on the fact that the RF produced by the TX the antenna is achieved and radiated by this completely
