MalThe resistor is there to deal with an unbalanced situation only. If everything is 'OK' then no current flows in the resistor. Don't be two weirded out by this circuit as it widely used on HF, VHF and UHF to combine antennas. On these bands one uses coax to make the 1/4 wave sections and the resistor is often omitted. 73 Scott hamilton mal wrote: Hi All Looking at the cct of the Wilkinson combiner there is a large 100 ohm Resistor involved. How efficient is this type of coupler and how much RF does the resistor eat up.What is the loss through the device? Those using the coupler will know the answer, and how were the values calculated for LF applications. 73 de Mal/G3KEV |
