I actually made this antenna to receive aircraft band or air-band. The frequency they use is from 108Mhz to 146Mhz. Thus this antenna will work as a charm if used for the purpose above or one can always use it for different frequency like amateur radio and will work just fine.
Step 1: Raw Materials
The things that you will need for assembly of this antennae are as follow:-
1. Aluminum sheet
2. Aluminum rods 5mm in dia 4.5 feet long (for preparation of this antennae and may vary according to frequency used).
3. A steel glass
4. L clamps (which can be made by the same Aluminum sheet)
5.Nuts and bolts
6.Antennae socket (bolt type). I found it from an old booster amp from a TV.
7. Wires, Hot glue and mseal
