step by step will be described how to make a EH- Antenna for the
20- meter Band.
if you are ready- go ahead with me!
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:
Tube ÐÐ-Í 32õ1,8 DIN 4102 B1 (dia 32-mm
and length 50- cm).
for the Tube 32ÐÐ S-16 (just to fit to close
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).
screw for plastic (wood) in length 10- 15-mm and several screw
in dia 3- mm and length 10- 15- mm with nuts.
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).
you could find buy a 2- meter length of
main cable with stranded wires in 1.5- mm dia (14-16- AWG).
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
Instead of Spectrograph
you may to use: Powerful RF Generator
or RF-Generator with RF- Bridge- for example, similar to
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.
