Below step by step will be described how to make a EH- Antenna for the 20- meter Band.

So if you are ready- go ahead with me!

 At the beginning we have to visit nearest Building Materials Store (Note I.G.: something like Home Depot).

 For making of the antenna you need to buy:

 Polypropylene Tube PP-H 32x1,8 DIN 4102 B1 (dia 32-mm and length 50- cm).  

Cap for the Tube 32PP S-16 (just to fit to close the tube).  

Copper foil two pieces by dimension 160-mm x 115- mm each (Note I.G.: In Canada I have seen such foil in local Craft Store). 

UA1ACO

Several screw for plastic (wood) in length 10- 15-mm and several screw in dia 3- mm and length 10- 15- mm with nuts.

3- meter length of insulated wire in dia 2-mm (12- 13- AWG) (Note I.G.: For Canada: Local Craft Store, Dollorama, Sayal, A- Z- Electronics).

If you could find buy a 2- meter length of main cable with stranded wires in 1.5- mm dia (14-16- AWG).

Do not forget find an RF- Socket in a special shop or your stock.

For tuning of the antenna you will need:

SWR- meter.Field Strength Meter.

Spectrograph

Instead of Spectrograph you may to use: Powerful RF Generator or RF-Generator with RF- Bridge- for example, similar to MFJ- 259B.

For experimenting with the antenna you will need a Q- Meter and C- Meter.

So all above mention parts are sitting on the desk. It is possible to make the EH- Antenna.
