Hello Rob,
You need one side closed with metal. Otherwise the signal would
probably go out both directions and have no power. And the length
matters since this is what focuses the wavelength. If I recall, when I
made mine, the Pringle's can antenna contains about 5 or 6 wavelengths.

Subject: [nycwireless] Sawed-off Cantenna?
I have a technical question:
Does sawing off the end of a Cantenna kill its usefulness?
My assumption has been it's only the diameter of the tube that matters,
not the length. Is this correct?
Here's the item I'm talking about:
