WebUpdate: Inverted V What if you arrange the antenna as an inverted V with the apex at 8m and the feed point and end point lower? The model shows that the vertical NVIS gain (at 90 degrees as this was designed primarily for intra-UK contacts) on 80m GOES DOWN about 2dB. Might be worth trying through, especially if it suits your garden better. WebJun 5, 2024 · It is adjusted to take into account the special characteristics of the inverted V. In the case of the inverted V we must add - to the list of environmental variables influencing the half-wave dipole - the angle between the two legs of the inverted V. The angle below the two sections of a horizontal dipole is 180 degrees. As the two sections of ...

The great thing about HF is you don't need somebody else's repeater radio. EFHW can be nearly any configuration. Try one, send some FT8, then go see your pattern on PSK reporter in real time. Then try another configuration. It's great fun. 4. DarkButterfly85 • 1 yr. ago. chicken perth

WebAs seen from the table, an 80 meter antenna at half-Wavelength Height should be at 129.5 feet. This is impossible for most amateur radio operators, therefore the modeling data that follows is based on a 12.2 meter elevation (40 feet). This is a practical maximum for commercial masts, telescoping poles and trees. WebMar 13, 2024 · My EFHW is cut for 80 meters, and the manufacturer states that it has low VSWR on every amateur band, all the way up to 10M. Using MMANA-GAL I modelled it in an inverted-V topology since this would … WebEasy Storage/transport. Stainless Hardware, UV resistant materials throughout.
