[TowerTalk] Preferred type of coax to be used for jumpers in a multi-operator room ?

[Stig Lindblom]

Gents; 

We are rebuilding a contest station operating room (HS0ZAR at HS0ZGD) and
need to do a lot
of new jumpers. 

Ref. advise below from K9YC (tnx) we will use RG400 (or similar) for
short jumpers. 

Considering to use RG214 (double shield) for longer jumpers, and for
coax-stubs as well. 

How is the measured, or experienced, shielding of RG214 compared to the
RG400 ?

Clarification for other readers. The center of RG142 is silver coated
copper coated steel, the center of RG400 is stranded silver-coated
copper. Both have double silver-coated copper braid shields.

Loss is about the same as RG58 -- in other words, fairly high. The
principal virtue of these cables is their superior SHIELDING, which is a
LOT better than most braided coax.  You only want to use this stuff for
short jumpers.

I've been happy with at least two purchases of Harbour Industries RG400
that I've found on ebay from a US vendor.  Harbour Industries is based
in VT, and has a presence across the border in QC. NA6O was happy with
the RG400 he bought from China.
