The original design assumed an infinite extent of ground. If we make our ground plane larger, does that help? Consider the mechanism that is responsible for the gain, as shown in the drawing below. Radiation from the center of the current distribution travels up at some angle as a direct wave. It also travels down at … See more One of the problems we often run into when trying to understand antennas is when a condition that applies in very specific cases gets generalized and accepted as “fact”, even in situations where it doesn’t … See more In December 1924, S. Ballantine introduced the 5/8 wave vertical in a paper titled, “On the Optimum Transmitting Wave Length for a Vertical Antenna over Perfect Earth”. He showed that, for a broadcast antenna over perfect … See more In the real world, many of us don’t live over perfect ground, or even over salt water (which comes close). I ran the same models over the typical soil in my area: The first thing to … See more Does this mean that the 5/8 wave vertical is the standard antenna for medium wave broadcast stations? No. Or at least, only rarely, since about 1934. It turns out that the high angle radiation increases fading, which limits the … See more WebGround Plane.

WebRegardless, a ground plane for a 1/4 wave monopole is only half an antenna. You will still have very reduced efficiency with any monopole shortened below 1/4 wavelength. As r/hobbified states, it will probably be OK for 10 MHz and above, with efficiency getting better the higher in frequency you go. http://hamuniverse.com/w5altgroundvsradials.html
WebJan 16, 2014 · The NEC (National Electrical Code) requires any metal antenna mast to be grounded to its own ground rod. The antenna ground plane or mount is connected to a ground rod only for electrical/lightning protection and not for receiving or transmitting requirements. Also per NEC code all ground rods need to be connected to the site …
