Cantenna or not Cantenna

I was looking for cantenna parts, the kind or antenna you make out of a Pringles tube.
The parts were hard to find, even at Fry’s Electronics, but then when we did find the parts, they were priced a lot higher than I had remembered from when we tried this a couple of years ago.
So off to eBay … there we found a couple of great looking cantennas for around $30.00 when you count in the shipping. The best deal came with 9 feet of cable. Bonus!
