You will need a center insulator for connection of the two quarter wave elements and the coaxial cable.Only the 432 MHz antenna is made from bare wire. Figure 2 — Vertical (blue) and azimuthal (red) radiation patterns for the hourglass antenna. As described here, the antenna is bidirectional. It can be made unidirec-tional by adding a 5% longer second loop behind it, as in a quad antenna, or by placing it in front of a flat con-ductive screen.The above delta loop design worked well on 20 metres and presented a low SWR when tuned. Minor adjustments to the feed point position and the length helped optimize performance, raising the overall height may further enhance antenna efficiency. Physical space limited me to the 20metre band, but the antenna did work well on this frequency.The tutorial of a DIY magnetic loop antenna for the amateur radio band featuring a remote tuning A magnetic loop is essentially a small loop antenna whose circumference is less than 1/10 of the wavelength.
