beercan antenna instructable

This is an instructable for a 1/4 wavelength broadband dipole with sleeve balun for DVB-T reception originally found here.

What you need:

• two empty  33cc beercans (or other cans that are not made of aluminium)
• a piece of 75 Ohm coax cable
• a coax plug

You will also need some sanding paper.

step1
Drink the beer, clean and dry the cans (use a hairdryer to speed it up a bit)

step 2
Roughen the bottoms of the cans where you need to solder.

step 3
Make a hole in  the bottom of one of the cans.

step 4
Strip 1.5 cm from the cable, solder the screen to the can, this should be easy.

step 5
Solder the other can, this is the tricky part...

step 6
Mount the plug and test. The cans fit in a piece of drain pipe.

I copied this table for Belgium from wikipedia

Depending where you are the antenna must be put horizontal or vertical.
