RF Sampler

My RF Sampler circuit takes input 2 volt peak to peak down to 14.26 millivolts for BNC connector out to oscilliscope.

Top is 2 volt AC input through 50 ohm coaxial cable to SO-239 connectors where RF Sampler routes off to the 47 Kohm resistor.  Right connector is where BNC connector goes to oscilloscope with probe on R  X 1 setting.

So,  if I multiply scope voltage by 140.25 I hope to be close to original input voltage, I hope.
