Please could you Help me find this Coax

Aurality · 8th April 2010, 12:04 AM

Hi I am trying to source some coax with the following specs...
wondering if it rings any bells for anyone?

75 ohm
Silver plate over copper,
single strand 0.6mm core,
Teflon dielectric insulating material between core and silver plated copper braid.
White Teflon outer covering

Any Ideas?

oh and a capacitance of 23pF per metre.

actually, I realise those capaticance figures are completely unreasonable,
so, lets just say lowest available.

Not sure what your cable is but it appears similar to Belden 1505A - a very common cable in the broadcast industry. 1505 uses foam center dielectric. 8281 uses solid poly but is quite 'ornery' to work with. Go to the Belden site and see what you can find. There are lots of different 75 ohm cables.

RG 179 / U coax is fairly close to what you specify, and is readily avalible and cheap.
