Any German speakers here?

You want coax that connects with Banana Plugs???

"Plus 8 Bananenstecker"

Norm

Good Lord.

He's selling it as *loudspeaker cable* !

It looks like a genuine RG type though.

Do you need 2 x 3 metre lengths and 2 x 4.4 metre lengths ?

Graham

He is talking about 4 cables each made of heavy silver-plated strands of copper (if that's what you call it in english).

translated :

high end loudspeaker cable RG214 silver line plus 8 bananapluga

insider tip from the nineties

the desccription of this cable is M17/75 - RG214 Heden Berkenhoff & drebes. You bet on 4 single loudspeaker cable (for a pair of loudspeaker)- consisting of two plus and two minus leads plus 8 bananaplugs.

This loudspeaker cable consistes of multiple massive thick silvercoated copperwires(no cheap flexible wires)

The leaghts are 2x3m and 2x 4.4m

The cable did cost 350 euros.

private sales - no return

Quite!

Oddly enough, that'd do very nicely! I actually need 3 x 610mm plus 1 x 860mm for my network analyzer's patch leads. According to Rene's translation, it appears to be the M17/75 mil-spec UHF stuff, too. :-\\ 26db/100m @ 900Mhz and swept. Of course, at audio frequencies, the loss would be negligible so it's easy to see why he's marketing it as such. So much more clarity than 'ordinary' speaker wire, too. :-)

Hello Paul,

Ok, Rene has translated it already. But I'd be careful when buying old coax for RF lab gear. Depending on where it has been the innards may or may not be that fresh. In the past I have seen some coax that had been used outdoors and had gotten a good soaking. At least I'd give the seller a ring to check on that.

If you need 50ohm coax why not go to the next ham shop and buy a length of new RG58? It'll hardly set you back more than bid and shipping on ebay and then you can be sure it's new, standard, and that you can get matching connectors right there at the shop. A good ham shop will have N-connectors.

A guy in the States that does a lot of metrology stuff e-mailed me and advised me to avoid RG58/RG8 and such like as it's not made to any decent degree of tolerance/precision. The stuff I'm bidding on is exactly the type he recommended for interfacing the VNA with the T/R bridge. There's not much on offer, but sufficient for my purposes, fortunately!

Sorry, I think my speakers came from China.

Thanks, Rich

In other words, if you want to spend a buck and a half on crap that you could find on the floor, go for it! :-)

Cheers! Rich

Precision ? What precision do you need ? What for ? The difference between RG214 and RG58 is the voltage rating. While RG58 is good for 1kV, RG214 is good for

Rene

I'm sorry to hear that, Rich; how awful. Tell you what, though - if I win the RG214, I'll send you half of it to connect up your Chinese speakers with. They'll sound brilliant. ;-)

Better than 4 degrees at 1.3Ghz.

Network analyser interconnects!

Well, there's never so much disagreement between engineers, it seems, than on the subject of transmission lines, feeders and antennas. I'll post you here the message I got from this guy (I'll snip his name out since it was an e-mail)...

Then tell us all why they didn't use RG/58 at 4 GHz on C-band satellite systems? The attenuation of RG/58 is horrible, even at VHF frequencies.

If you want accurate data from a network analyzer the cables have to exceed the specs of the analyzer. We used semirigid cable with soldered on SMA connectors to test and align tubular filters in the VHF frequency range. We used a pair of very expensive "N" to "SMA adapters on the front panel of the various HP network analyzers to connect the test cables to the unit being tested or aligned. We built the tubular filters in house because the lead times were too long for custom frequencies.

RG58 is only single shielded by the way, too.

Rene

I don't really follow this 'speaker cable' nonsense; but I do recall a year or two ago at some European Audio show the winner of some professional award for woderful audio was asked what he was using for his speaker cables at the show and responded that he was using extension cords from the local hardware store.
