RW4HFN Limited Space Antenna for the 20- meter Band

RW4HFN Limited Space Antenna for

the 20- meter Band

By: Igor Vakhreev, RW4HFN

It is very interesting variant of a mono band antenna for the 20 meter band installed on to a balcony. The feature of the antenna is that it has DD opposite to the building. It means the antenna cannot pick up the hum from the electronics devices located in the building and the radiation of the antenna cannot go towards the building and does harm to the electronics devices located in the building.
