SWR bridge
It is possible to measure return loss up to 1000 Mhz, the return loss range is 0-50 to 0-40dB depending on frequency

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

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
