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
Step 2: Cutting the plate and fixing nuts and bolts
Now drill four more holes just at the sides of the antenna hole for the screws to fit as shown in the picture. Drill more holes for the aluminum tubes that will be fixed later for the array of stick. Add the four nuts and bolts on the four holes that were made one by one as shown in the diagram.
After the small base has been added it should be noted that the two holes should be perpendicular aligned with each so that the aluminum tube can easily pass these holes.
