[TowerTalk] How to solder aluminum braid coax cable ?

[Yan (XV4Y)]

Hi,

A few years ago the cable TV network of the city went bankrupt.
They left kilometers of then unused cable on the poles.
Yesterday, the telephone company guys did some clean-up on the poles (they are really messy so it was welcomed) and threw away trunks of coax cable.
I took two runs of around 10 meters each, just in case.

The cable is Chinese made, and the only roman characters inscriptions are SYWV 75-9.
Doing a quick search on internet you'll see its official spec are reasonably good with 2.3dB/100m losses at 50 MHz.
It's a 75ohms cable made for up to 1GHz signals. (right choice for cable TV, isn't it ?)
PVC insulation, PE foam dielectric, copper center conductor BUT aluminum shielding...

Braiding is very low density (not for high power transmissions) but I will use it with 100W anyway.
I think it should be a good replacement for the RG-6 alike cable I've been using for the 20m verticale with fair success.

However as the braid is in aluminum, I wonder if any of you as some advices on how to solder it ?
I've been using the cheap RG-6 cable TV a lot when good 50ohm cable was not available.
However, soldering the braid (and at time the coper coated center conductor) has always been tricky...

Thanks for your help.
73,
Yan.
