Further to my previous post regarding laptop problems, during which time I mentioned I had a cheap Ebay yagi in the mail, it has arrived.
It's actually quite good, reasonably well made, and no complaints about quality v's price.
I already had a bit of web info up on corner reflectors, so I added the test results to that page.If anyone's interested have a look and see what you get for $25 AUS.
Incidentally the large gap near the driven element as mention by Jeff L(displayed on the Ebay ad) is not a feature of the unit I received.
It appears to be a suitable toy for tinkering with, and money comparatively well spent :-)
