I could mail you some, but there's bound to be someone closer that
could get it to you faster.

Another option: crimp on an "F" connector and solder an F socket to
the board (perhaps with short wire leads, if the frequency isn't too
high).

You can also get solder that works on aluminum, but that might well
take longer than getting coax with copper braid. BTW, I have Teflon
RG-6-type that has solderable braid (plus foil).

Cheers,
Tom

Hello, in need of some urgent help. I am having a horibble time
soldering
the shield of a coax cable to a copper pad in a circuit. I just can't
get
the solder to flow on the shield. What can i do? I don't know if it
matters but the shield has the appeareance of aluminium. I"m hoping
this
isn't what it is but really dont' know. Please help. Thanks in advance

Are you trying to solder RG6? Easiest fix is to go buy a piece of RG59, if
you need 75 Ohm coax, or almost any 50 Ohm coax. I gather there is no wire
braid over the Al foil.

Thats what i found out today. That its all RG6 locally ex. homedepto
radioshack. I can't seem to find any other sources (i'm at lehigh
university in PA in case anyone is close) I only need at most 2 feet of
this. Would anyone be able to ship me some if i were to cover shipping or
think of an alternative. I have a 2.4 ghz wireless network up right now
which i need to attach a home made antenna to. Aside from the antenna and
wireless transmitter all i have right now are f-connectors and a lot of rg6.
The antenna and card are still connectorless. I"m open to any solutions
some one may have. thanks in advance

If its RG6 then it does have a continuity wire, you have probably
nicked it off in stripping back the outer sheath. The best given so
far suggestion is to use a twist on "F" connecctor - unless you can
borrow the proper crimping tool for crimp connectors. BTW, cable
losses at 2.4GHz will be astronomical, virtually nothing will be
getting up to the antenna. - or is it 2 feet from the card, then
acceptable. Even so, RG6 has the only virtue of being cheap, with
highly variable quality. have a talk to the engineering department at
school (if there is one) or do a internet search for a local 802.11
group near you, they are usually glad to assist in these cases. If you
have lots of money, get a USB wireless card and put it on the back of
the antenna, you can then run heaps of cable out and so get it to a
high spot.
