Get hold of a simple broom-handle. Alternately you can make use of a dowel rod or ready-made plastic tubing that’s available from a plumber or a builder’s merchants

The thickness of the rod is not paramount and anything from about half an inch or better will function perfectly well
Create a relatively large base to hold the rod vertically. The base should be heavy enough to keep the rod vertical at all times

Get hold of an aluminium disk with a minimum 6 inch diameter. A disk of approximately 12 inches seems to be the optimum size. The disk will provide a capacity hat termination and will help in reducing any noise pick up

Source a quantity of no.16 PVC plastic covered standard wire. If this is not possible then a good alternative is no.16 or no.18 enamel covered copper wire. If this is not available then standard no.18 speaker wire will do With one end of the wire connected to the disk, begin winding a consistent coil around the rod. The coils should sit next to each other and be bound tightly to the rod. On completion of binding the rod you should then terminate the wire either by connecting it directly to your antenna tuner or by a proprietary wire connection terminator. Ensure that the wire extending from the base of the rod is as short as possible On completion you can protect your antenna by coating it in proprietary insulation tape or by giving it several coats of protective spray

For optimum performance ensure the antenna is placed close to a window, in a garden or veranda. Ensure that the connection from the base is as short as possible

You can use your antenna without a dedicated tuner, however there will be a lack of enhanced core quality if the antenna is not attached to a receiver via a bespoke dedicated tuner

Your new antenna is now geared up for use

This simple wire-wound antenna will provide a great basis on which to trial your experience. Providing a ground link to both the antenna and tuner will optimise the system. A simple technique of creating an artificial ground is to connect a minimum 5M strand of wire which you allow to fall on the floor of the room or garden.
