Sunday 8 October 2023. I decided to dust the cobwebs off my homebrew EFHW antenna for an activation of the 2nd most popular VK summit, Mt Stromlo VK1/AC-043, 782m ASL (2566 ft). This EFHW version covers the 40, 20, 15 and 10m bands, I am planning to add a link for 30m later this week.…
Homebrew HF EFHW antenna for low power SOTA, Parks and field day events. Using a 19.8 metre length of wire mounted as an inverted V, a non-resonant 6.8 metre counterpoise, this antenna is resonant in the 40/20/15/10m bands. At 19.8 metres long, the VSWR is less than 1.5:1 in the voice segments. If your primary…
QRP Multi-band HF EFHW antenna for SOTA Post updated 29 September 2017. I have inserted two additional links for coverage on 17m and 30m. I have changed the counterpoise wire from 1.5 metres to 6.8 metres long. My take on a QRP HF EFHW inverted V antenna designed for use on five amateur radio bands…
