Hi Chuck, indeed I was thinking with the logic of building wideband transmission line transformers which cannot be easily built with such a high transformation ratio. As far as I understand you would put the capacitor at the antenna side. If I wanted to put the capacitor on the low impedance side , let's say at 10Mhz, what would you do? Which value of reactance should be on the low side?

When you measure VSWR you are measuring reflected power. The less reflected power, the lower the indicated VSWR. When you measure a transformer (or attenuator, or feedline, or any circuit element) with 100% loss, there is no measured reflected power. All of the forward power is absorbed by the circuit element and none is reflected. A VSWR bridge sees no reflected power and reports VSWR = 1:1.
