For a long time I have wanted to incorporate some beautiful high power components salvaged from the defunct transmitting site at Rjúpnahæð into my station.
3-1/8″, 50-ohm Standard Rigid Line manufactured by Andrew has a Peak Power Rating of 900 kW and attenuation of 0.033 dB/100m at 1.0 MHz.
In the center of the line I put a Line Sampler with 60kW BIRD sampling elements and at the far end of the line a 100kW Coaxial Transfer Switch.
One port of the Coaxial Transfer Switch goes to my Rhombics (40M-10M) and another port goes to a Dummy Load with a 5kW rating. The unused port becomes active for antenna measurements when the output from the transceiver/amplifer goes to the Dummy Load. This could be useful for attaching an Antenna Analyzer.
The power used at TF4M is 1 kW.
