Will a high SWR blow up my transmitter"
Where the energy really goes in an antenna system, Will a high SWR blow up my transmitter?
Wattmetro/ROSmetro automatico 1.8 - 60 MHz
Lo strumento fornisce una misura piuttosto precisa nelle bande HF e VHF fino a 50 MHz, entro un range di potenze compreso fra 5 e 120W
Wattmetre de -60 a +60 dBm et mesureur de champs
Build my wattmeter myself. The option chosen was to make a directional coupler which would take approximately -50 dB from the signal to be measured. 60 dBm 1kW
Led Swr Bridge
An LED SWR bridge is almost always used with an antenna tuner

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
