Of course anyone’s experience may vary, but over a period of years I have made purchased dozens of purchases from both AliExpress and Banggood. I have never had any issues with either group. However

Similar story on AliExpress out of China on a few orders. In this scam the vender would issue a FedEx tracking number that would show delivered, after some time. However, in conversation on line with

I agree, Paypal is UNSCRUPULOUS, disagree?? Read the story about the guy that made a huge buy of 18650 li-ion cells and then got SCREWED by Pay@$#^ because they (Pay@#$^) wanted to hold the payments 6

Yes, I think we need to use payment methods that offer protection for unscrupulous sellers. And PayPal is a good example. ?n joi, 24 nov. 2022 la 00:33, John <ve3kkqve3kkq@...> a scris:

I realize that this bit of advice is too late, but always buy from the OFFICIAL vendor. I had a similar experience with a "really good deal" on a Chinese VHF mobile radio. I was very excited to

Unfortunately, such situations have also appeared on Aliexpress. Fictitious tracking numbers, seen only by them. Shopping in China has become an adventure. The biggest loss I took was 120 USD, but I

I purchased a model SV4401A 8-inch VNA from eBay seller Hui3165 on Oct 24 because their price was much lower than any other supplier. I followed the tracking on SpeedPAK Standard from China to my

I ran some quick NEC models, results attached. The R doesn't change a lot until you get outside, say, 0.3 to 0.7 split point (0.5 in middle). This was a dipole "cut" for 10 MHz resonance. And the

One might want a transformer (which could serve as a balun or RF choke) on an OCF dipole, because the resistive impedance at resonance is typically quite high, compared to 50 ohms. OTOH, if the

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
