So I wonder what truly horrible coax would look like

Here's a comparison for loss between RG-400 as measured by K9YC and
RG-174/U per mfg specs.

The RG-174 is Belden 8216.  Per the datasheet, "26 AWG stranded (7x34)
.019" bare copper-covered steel conductor, polyethylene insulation,
tinned copper braid shield (90% coverage)".


I was thinking more about "poor quality" as opposed to "inherently lossy" - I'd expect small coax to have higher loss (people even use it as a dummy load at microwave frequencies)
