G5RV vs Alpha Delta DX LB Plus

Presents SWR analysis of an Alpha-Delta DX-LB Plus multiband wire antenna, installed as an inverted-V at 40 feet with ends at 15 feet, using an RigExpert AA-54 analyzer. The resource provides a full SWR sweep from 0.1 MHz to 54 MHz, followed by detailed SWR graphs for individual amateur bands including 160m, 80m, 40m, 30m, 20m, 17m, 15m, 12m, 10m, and 6m.

The analysis highlights the narrow bandwidth on 80m and 160m due to loading coils, necessitating tuning for specific operating frequencies. It notes excellent SWR performance across the entire 40m band and good results on 10m, also requiring tuning. The author shares personal experience with the antenna, including a 17,000 km QSO on 20 meters, and discusses plans to replace it with a homebrewed parallel fan-dipole.
