Chep Chinese Mass Produce Antenna?

[ka3jjz]

I would read the article (use Google Translate to change it to German if needed) - and look closely at the very bottom of the picture of the 2 loops at the top of the article. The 'base' that holds the antenna in place is different between the two

These should pretty much be identical in performance - they appear to nearly be clones of one another. That's not really a surprise...the article says very clearly...

To prove this once again to myself I compared several loops….the Tecsun AN-100, Grundig AN-200, Terk AM Advantage and Select-A-Tenna Model M with a few radios and in all cases they were virtually indistinguishable from one another.

I have a balun at home. A friend of mine gave me it without any instructions.

What a great friend you have!

I have the AN 200 Antenna from Tecsun and it works
very well by placing near a Radio with an internal AM
Antenna ..
And it also has a 1/8 jack for directly plugging in ( yes you need different adapters sometimes) to Radios Ext Antenna jack - such as Eton E1 and others with no internal Ferrite Antenna.

Ok and what does I need to connect the Antenna to my SDR Dongle?

 

[ka3jjz]

Without knowing precisely which SDR and upconverter you have, I would hazard a guess at a 1/8 inch (3.5mm, I think) male phono plug to a male SMA (most of the RTL dongles have a SMA connector, I think. Depends on what the upconverter uses...). As it appears that it comes with a cable with the 3.5mm on one end and bare wires on the other, you would need to solder (or crimp, I guess) a proper SMA male jack.

one of that plug: rtl2832u r820t2 | eBay
dont ask me who make it. Chinese stuff.
And this upconverter: Upconverter für SDR Empfänger - HFTechnik

Unfortunately the pic of the upconverter cuts off the image of the SMA jack on either end - it almost looks like those are SMA Male jacks, so you would need a SMA Female jack on the end of the cable that comes with the AN200; but that's just a guess on my part

It look like the ship it with an normal Audiocable and not with a SMA Adapter?!

 

[ka3jjz]

Well a 3.5mm jack is pretty cheap, and we're not talking about professional grade here. The only issue I see here is that there are 3 wires - one must be hot, another a ground and perhaps a neutral. Hopefully the manual explains what these 3 wires are. It should then be easy to wire the SMA provided you have the right tools

"And this upconverter: Upconverter für SDR Empfänger - HFTechnik"

The pcb connectors look like standard SMA female jacks, use standard SMA male plugs on cables. (unless they are Rev Pol)

Just match the other end to what you are connecting to.....

So I got the Antenna how to connect the Cable to my SDR?
