The "Slingshot" Antenna
for 2 Meters
The completed antenna is bi-directional with a rough figure 8 pattern and is composed of 2, 3/4 wavelength sections.
The antenna is bi-directional with a rough figure 8 pattern and is composed of 2, 3/4 wavelength sections.
You should note that the bottom (horizontal element portion) is 1/4 wavelength long and the top (vertical element section) is 1/2 wavelength long. This design, untrimmed, up a half wave, presented an SWR of 1.5:1 across the top 2 MHZ of the band (144-146mhz)".
