With this antenna the coverage is 80,40,20,15 and 10 meter band without any antenna tuner and the average SWR is below 1.2 on phone bands. The total antenna lenght is about 23 meters , with one 20.4 meters long segment from the 1:49 transformer to the 110uh coil and about 2.2 meters long segment from the coil to the insulator. -
Andrew Georgakopoulos, SV1DKD, modeled the End-Fed Half Wave (EFHW) antenna using MMANA-GAL software. He evaluated the EFHW-8010-2K from Myantennas.com for field operations, comparing it to random wires, OCFD, and dipole antennas. His results showed similar performance to OCFD, confirming EFHW's practical feeding advantage but with potential high-voltage risks at the feed point
