DEWD Vertical for the 80- meters

The publications devoted to the memory of UR0GT.

By: Nikolay Kudryavchenko, UR0GT

Variant of a DEWD Vertical Antenna for 3.5- 4.0 MHz looks astonishingly simply. Just one wire in diameter of 2- mm and 18.04 meters long is installed on the distance 74- cm near a Vertical Antenna with diameter of 60- mm and height of 20.6 meters.

This additional wire should be connected to counterpoises or to other (common with the Vertical Antenna) grounding. The simplified model of the antenna (file DV3.5_4MHz.maa) without counterpoises ("ground" does the job) may be loaded:
