[quote:332e407348=”12vman”]Let’s say that only 1/4 of a ground array was laid out from a central point (like a 1/4 of a pie..30 radials.. or more) at 0.41 wavelength per frequency. Would the antenna react to the area of the less resistance (ground resistance) and cause a lobe in the direction of that area.. making it somewhat directional? Would the majority of the radiated power be drawn towards the ground area?[/quote:332e407348]
Repeating what I wrote a few posts earlier in this thread, “the most important benefit of the ground system is to reduce ground losses for the antenna system. Asymmetric placement of the radials around the base of the radiator isn’t ideal, but if the radials that can be installed minimize ground losses for a given installation, that will maximize the radiation efficiency of the antenna system for that situation.”
If the radials are missing over some sector, that will increase total ground system losses — meaning that less power is available to be radiated by the antenna. But that will reduce radiation in all directions, not just where the radials are missing.
