20m Projects - Dipole Antennas

Click to enlarge20 mtr Half-Size Dipole Antenna /A> by N4SPP
A full-size ( = ˝λ) dipole antenna for the 20 mtr band spans about 10 meters (33 ft). One of the 20 mtr antennas that I built is a half-size 2-element "yagi" beam antenna, based on a design by Gary Hanson (KJ5VW). The "driven element" of such antennas is a dipole.

Al meer dan 5 jaar geleden heb ik al eens een paar goedkope traps gemaakt en er een klein stukje over op mijn website gezet, met de ontwikkelingen dat de Novice amateurs (binnenkort) op HF mogen leek het me eens een leuk idee om het netjes uit te werken.
