[inertial]

HI, I'M SEARCHUING ONE PLACE TO PURCHASE 100 FT OF ALUMINIUM SHIELD FOR MAKE MY SIGNAL SHIELDED CABLES.
ALSO I'M SEARCHING SOME MU METAL BEND OR SHEET AT GOOD PRICE FOR MAKE MY 5 PAIR OF SIGNAL HIGH QUALITY CABLES GFOR MY SYSTEM.


THANKS IN ADVANCED

Hi, Paolo.

Adhesive aluminum tape is sold in plumbing stores a very cheap price.

Best regards,

What type of cables are we talking about?

 

[s3tup]

Rigid type i'd guess, (moo metal use). Ah, yo'll need to bake 'em every time you bend 'em.

Could we have a collection so that the OP can buy a new keyboard. His current one clearly has a stuck Caps Lock key.

Mu metal is fine until you bend it. Then it stops working and needs to be heat-treated again.

Last time I looked aluminium shield was available in quite long lengths in most supermarkets or kitchen shops.

Hi!

As in Italy this is not available (aluminium shield), can I ask a link to someplace in Europe that sell it?

Thanks!

In the US the big-box home improvement stores have adhesive backed aluminum tape (3 to 6cm wide) in the wall or window insulation dept. and the furnace duct dept.

Automobile parts stores have heavier tape in the body repair and muffler repair departments.

The bad news is that none of these can make as good a cable as the major wire manufactures.

Shhh! You might offend someone.

Is there any downsides on using aluminum cooking foil as far as thickness and RF is concerned for interconnects? Or is it a win win situation if properly terminated and grounded

see post 8

Making your own cable is every bit as barmy as making your own capacitors, but somewhat easier than making your own semiconductors.

I'm working in EMC at the moment. We use copper foil tape for shielding cables. Aluminium foil does not perform well. Earth bonding is better with copper. Conductor Emissions are better with copper. Radiated Emissions are better with copper. Plus you can solder wires to copper easier than aluminium.

Where I can find copper foil?

Thanks!

Buy shielded cable, you will get a better result and probably cheeper by the time you have finished messing about.

First read posts #8 & #14.
But copper foil is useful in other DIY electronic areas.
So I get mine in a hobby/crafts store that deals in leaded & stained glass.

OK thanks!

tricky to solder aluminium

Copper roof flashing is VERY common in the construction industry and is available in rolls.

You could also take some RG58 type coaxial cable and pull the center conductor out of it, then you will have a tinned copper "Jacket" to work with.
Larger coaxial cables could be used if you need a different diameter of "Jacket".
I like RG400 since it is silver plated over solid copper.

You can get sticky backed copper foil for electronics, I have a couple of rolls of it, when I remember where I got it I'll let u know, might have been RS or Farnel!
