The Wonder Wand Whip looks similar to a Miracle Whip. It mounts directly on the back of the radio using its integral PL-259 connector, and has two controls that face forward for ease of access.
The lower control is a bandswitch which has eight positions, marked 1.8-3.5, 7, 10, 14, 18-21, 24-28, 50 Mhz.  These positions select taps on an inductor, according to the amateur band you want to use.
The upper control is a rotary control that is continuously calibrated from 1 to 10. This is a tuning capacitor that is used to tune the antenna for maximum signal and minimum SWR on the selected band. The tuning is quite sharp and this control allows the antenna to cover a wide range.
On top of the antenna is mounted a 7-section black telescopic whip 125cm (50 inches) in length.
The whip antenna in the last version is removable.
A counterpoise is required for best results it is not particularly critical. A wire can be used to ground the antenna to the copper pipes of a central heating system. When used out of doors, a few metres of wire laying on the ground is generally all that is needed.
