On the surface the Rig Expert is easier to use to test antenna systems but not much more. Also, there is no apparent calibration needed for the Rig Expert but this assumes you are connecting directly

I also use the Harbor Freight cases for my Nano and Tiny SA Ultra, adaptors. Cal kit, and cables. gmail.com@groups.io> wrote:

In my experience using a 33 material gives better bandwidth than the 43 material. Also. I think 12 turns is a bit much if you are not interested in 160 meters. You want to keep each turn of coax as fa

I will add my input here as well. I like things that are as simple as possible. 1. Measure a length of the cable in question and note that length. 2. Set up the NanoVNA in the Time Domain Reflectomete

I have had reasonable luck with these cables. *Clyde K. Spencer*

Using the short cable also helps to reduce strain on the SMA connector. *Clyde K. Spencer*

I agree with your statement regarding the return loss/VSWR if great care is taken in their installation. Especially below 30 MHz. Have you tried purchasing a short, 6 to 8 inches, SMA male to SO239 Fe

Glad it worked out. I will keep that in mind if my unit goes spooky. *Clyde K. Spencer* wrote:

Another thing to consider is the materials in the roof. How do they impact the antenna tuning and performance.Just like getting height above the ground is important so it will be with the roof. *Clyde

Try viewing this YouTube video for measuring bandpass filters. https://www.youtube.com/watch?v=hf4grkMuql4 *Clyde K. Spencer*

Of course the Anritsu is far better. The Anritsu is a professional instrument and would have far better specifications. It does cost far more than the NanoVNA.

This would get a better response if you posted it on this link. nanovna-f@groups.io *Clyde K. Spencer*

Make sure you enter the VF as a percentage not a decimal value. EXAMPLE 60 not .60 *Clyde K. Spencer* wrote:

one has to consider the environment, not discussed prior in this thread. If there were any metal or other electrically conductive material near the antenna when tested that could be a possible cause f

If you are sweeping across all bands the antenna is designed for as the NanoVNA sweeps across each resonant point it will indicate the SWR for each band. If you had a fan for 40, 20, and 15 meters the

One of the lesser known issues is transmitter sideband noise. No carrier is perfect as it generates noise eithe side of the carrier and if the carrier is very powerful so the sideband noise is conside

Hi Chet, I am glad to see you are still out there. KD8AN *Clyde K. Spencer*

The-F model has a 4 inch screen with either the rocker switch or pushbuttons depending upon models. Hugan made an original VanoVNA that was small and had the rocker switch. *Clyde K. Spencer* sky.com@

When talking about the DeepVNA 101 you need to use the NanoVNA-F groups.io link. nanovna-f@groups.io *Clyde K. Spencer* gmail.com@groups.io> wrote:
