Sampler question

I just purchased a scope and it will be here this week. My question is looking at samplers to monitor my signal. Been looking at a couple of samplers. Anyways, one fits the Bird 43 and is at -50dB and the other screws on to the side of bird meter and has a higher wattage rating, but is only -40db. I don't really understand the db thing and how will this affect signal? I know it reduces signal. But that's about it. Can anyone explain this to me please? Or at least send me in the right direction.
 

Looks good, thank you. Still gonna get the others I was looking at, but i really like this and will build one of these as well. The sampler I was looking at is rated at 25kw pep.Should be about 2500W average. Nuffsaid.
 
You can also just wrap a wire around the coax!

Or you can just use a T-fitting, if your getting to much power to your scope just clip the center conductor going to the scope.

hey, thats a great idea. Like the inductive coupling idea of just wrapping wire around coax to get idea.
 
That design especially works well with lower power levels when the proper mix is used in the core.

Needs a footnote to terminate the cable to the measurement device. Otherwise have fun tracking down RF problems and/or weird envelope patterns.

Yeah, I was wondering what mix and if a certain length or ohm cable needed to be used and if a certain amount of capaictance or a trimmer type might need to be used. Also I assume less turns on ferrite would make it less sensitive for pick up coil?
