Longwave Information Details of my 136 kHz station
Umbrella-Antenna It consists of a 18m vertical telescopic fibre glas mast height depends on the wind condictions, four top-load wires, each about 15 to 20m long at a relatively steep angle

Measuring SWR
SWR standing wave ratio) is a measurement of how efficiently your antenna system will radiate the power available from your radio
