anyone does have any experience in such materials? (copper, aluminium, brass, etc)

Best regards

Hi, I looked into building a QFH some time ago and found a few articles on the web. Most seem to use copper water pipe, used in the airconditioning industry. I also saw one using coax cable which I started building but like most projects never finished. I use a ground plane style antenna made out of aluminium rod with a LNA but I don't have a very good site and can only see in one direction which limits reception somewhat.
Here are a few links
