I have a triple conductor RG-59 type coaxial cable used in analog cctv. I intend to use 2 meters of the cable. I have a gm probe at one end and the counter circuit/HV circuit at other end. Do I need to place Ranode, Rcathode and Coupling capacitor very close to GM tube itself ?
Will cable anyways effect pulse shape ? What is the best suggested way for long probe and high count rate ? Approx 1500CPS ?
