Efhw inverted v

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 ...
