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? 


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!


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
5kV or so.
