The OCF set of wires is NOT a balauced (differential mode) source/load! Why use a balun? A balun is a circuit element intended to transform differential mode (dipole) to common mode (coax). An RF

You MIGHT be able to do it with 2 measurements. Use the TDR function to measure one section (lelement) and then the other section. I assume that you would have to reverse the NanoVNA's connection to

... You have to feed ocf with a 1 to 4 and a good choke Measure over a halfwave (or multiple of) cable (to see same resistance as on feedpoint). Easy as baking cakes. DJ0IP made several dozen ocfd

Getting back to the original question - can you use the NanoVNA to determine where the feed point is in an offcenter dipole: NanoVNA can easily determine resonant frequency (where X=0). Onc

Just to check —— The resonant frequency of any dipole (center fed, OCF, or end-fed) is determined only but the TOTAL length of the wire, and not be WHERE you feed it. (And maybe how high above

this is a really good article on ocfd at various different places. seems you can select from about 20% to over 33%. All depends on your prefered frequencies.

OCFD puts the feedpoint at 5/8lambda from one end. That would be about 81-82ft for a 80m antenna. Stephen W9SK

Hello! How can we use the mighty nanoVNA to identify total length of a Off Center Fed Dipole (OCFD)? Or Normally a 80m dipole is about 130 feet the sides are 130/2. Can the nano measure the total

Dear Mr.Berry, Hiii. Am VU2BOA handle Sam from South India. Just purchased Nanovna - H. Just wanted to know how the return loss of an antenna is done using Nanovna -H. Will be highly thankful if you

Fabulous! Sir thankyou so much

This is a perfect application of the nanovna. If your nanovna has a recent version of firmware, I think 1.1 or better, it will have a "measure" item on the top menu. Select that, and choose the

If anyone can help with a guide or instructions, I need to cut a 90deg phasing stub for 7.04mhz using my nanovna. Really didnt see much on youtube? Can anybody help, please?

READ BELOW about VAR AC I would like to suggest that tonight’s *Five County Digital Training net* (7 pm Nov 21) finishes up our discussion of the *Nano VNA* apparatus. We have covered the basics

Found the problem. From a post on github (https://github.com/espanso/espanso/issues/1122) I found that the settings for antialiasing had been depreciated. By editing

Downloaded NanoVNA Saver 5.3 and loaded it on Ubuntu 22.04. Get this error message upon running the app: Settings schema 'org.gnome.settings-daemon.plugins.xsettings' does not contain a key named

OMG OMG OMG... thank you so much i unbricked my NanoVNA-H4 using the section "FIRMWARE UPGRADE USING NanoVNA-App for Windows by OneOfEleven" in the absolute begirners guide. thank you so much again

Hi, DisLord made a great job again, and S11 works great in 1.2.14. Uwe, DL4AC
