Rosmetro con accoppiatore a due toroidi
Costituito dai due trasformatori T1 e T2 , ognuno con una spira sui primari, costituita da cavo cossiale, e da N spiresui secondari opportunamente collegati
Setting the SWR of Your Antenna
SWR standing wave ratio, is a measurement of how efficiently your antenna system will radiate the power available from your radio
Simple 2.4 GHz SWR Meter
A simple 2.4 GHz SWR meter which is based around surplus microwave hardware which can be easily found
Simple RF Power
The board shown here has two separate detector circuits on it, and is the one I now use for monitoring both forward and reverse power with a dual directional coupler, and for providing an SWR trip signal
