Related question: Assuming I'm using 10MHz sine wave. What's the best physical cable to use? Is there any good reason to use 50 ohm cable? What about 75 ohm? I looked at a schematic of my counter and it looks like the 10MHz signal hits some high impedance chip inside. RG6 seems like the way to go. It's double shieled and lots of cable TV parts could be used.
