Joe, Another good way to learn about the NanoVNA is to read old posts in this group. Many typical questions have already been answered. For example this post which deals with your question.

Joe, The best way to learn about your NanoVNA is to "learn by doing". Calibrate your unit for 3 to 30 MHz. and make a measurement of a narrow band like 40M by zooming in. Then calibrate for just the

Thanks, I was thinking of something like that. Joe WB9SBD

Always calibrated however, unit does interpolation. Therefore, if you desire best accuracy over a given range, then cal over THAT range.

Ok, say I set up Stimulus for 3 to 30 Mhz. And then do a calibrate Open Short load. Now it is supposedly calibrated for anywhere between 3 and 30 Mhz correct? Now I look at the who range and decide to

OK, that's adjustable for different jacket/braid/dielectric/center diameters, do you have to swap the cartridge for different strip lengths? 73, Willie N1JBJ

Paladin CST Pro https://www.techtoolsupply.com/TempoCST-Pro-Stripper-with-Blue-Blade-p/gre-pa1283.htm looks like it

3 blades cut jacket, shield,dielectric. I enjoy mine.

Hey Jim, Do you have a pointer to the fancy adjustable one? I've been having a hard time finding anything other than 2 and 3 blade non-adjustable ones 73, Willie N1JBJ

Yes, I can calibrate the device, but when doing measurements, I get a lot of lines in a mess. If you have a look at the photo - measurement - you can se a curve form, but rather thick. The form of the

I have tried 3 different calibration sets, they all get the same result. Measuring at DC is ok. My NanoVNA is a SAA-2N, this is a device with N-connectors, so I don't think they have don their job...

It would depend on what coax you are working with. Lately I've been using RG316, quite by accident I discovered that I can neatly remove the outer jacket with my Ideal strippers by using the 14AWG

It depends what you mean by pro. While I was working for a cable provider the service men used cheap tools like these: https://s.click.aliexpress.com/e/_AmaRuK https://s.click.aliexpress.com/e/_9QEcIK

That's why I eventually got the fancy adjustable one.? I had a single

For instance, this is still a work in progress, but, for RG-8x: BNC Connectors from HRO: Lands Precision BNC-10Z-DGN https://www.hamradio.com/detail.cfm?pid=H0-009969 N-type for RG-8x:

I tried to find some catalog info, but you need to dig through distributors pages.. There's different flavors of these things. 2 and 3 level stripping, adjustable or not, whether are not you handle

Check your cal loads with an ohm meter to see if they are OK at DC. Take a look at the inside socket of the SMA connectors. Perhaps "drilled out" by rotating pin after too may uses. Roger

Dick, Does the article indicate how much "blow-by" you get (due to the mechanical switches in this design) as the frequency increases? Roger

One of those multiblade spin around the coax I've used a Paladin CST for decades.

I have a ratchet crimp connector and can install various types of terminations. But what tool(s) do the pros use to strip coax? Any suggestions?
