Saw this and wanna share with you, how to design a workable cantenna. It is so called because the material involved in which it is made from is an empty can for beverage or something.
You should be able to have
something like this at the end of your practice.
Tools required
*
Can opener
*
Ruler
*
Pliers
*
File
*
Soldering iron
*
Solder
*
Drill with a set
of bits for metal (with a 1.5 cm diameter bit)
*
Vice or clamp
*
Spanner or monkey
wrench
*
Hammer
*
Punch
Construction
1. With the can opener,
carefully remove the upper part of the can.
The circular disk has a very
sharp edge. Be careful when handling it! Empty
The can and wash it with
soap. If they can contained pineapple, cookies, or
Some other tasty treat, have
a friend serve the food.
2. With the ruler, measure
6.2 cm from the bottom of the can and draw a
Point. Be careful to measure
from the inner side of the bottom. Use a
Punch (or a small drill bit
or a Phillips screwdriver) and a hammer to mark
The point. This makes it
easier to precisely drill the hole. Be careful not to
Change the shape of the can
doing this by inserting a small block of
Wood or other object in the
can before tapping it.
3. With a small diameter
drill bit, make a hole at the center of the plate. Increase the diameter of the
hole using bits with an increasing diameter.
The hole should fit exactly
the N connector. Use the file to smooth the
Border of the hole and to
remove the painting around it in order to ensure
A better electrical contact
with the connector.
4. Smooth with the file one
end of the wire. Tin the wire for around 0.5 cm
At the same end helping
yourself with the vice.

Transmission Lines
Figure 4.37: Tin the end of
the wire before soldering.
5. With the soldering iron,
tin the central pin of the connector. Keeping the
Wire vertical with the
pliers, solder its tinned side in the hole of the central pin.
Figure 4.38: Solder the wire
to the gold cup on the N connector.
6. Insert a washer and gently
screw the nut onto the connector. Trim the
Wire at 3.05 cm measured from
the bottom part of the nut.
7. Unscrew the nut from the
connector, leaving the washer in place. Insert
The connector into the hole
of the can. Screw the nut on the connector
From inside the can.
8. Use the pliers or the
monkey wrench to screw firmly the nut on the connector. You are done!
As with the other antenna
designs, you should make a weatherproof enclosure for the antenna if you wish
to use it outdoors. PVC works well for the
Can antenna. Insert the
entire can in a large PVC tube, and seal the ends
With caps and glue. You will
need to drill a hole in the side of the tube to accommodate the N connector on
the side of the can.
Your finished antenna.
