A monopole antenna requires a proper ground plane (such as radials or a metal surface) to function effectively; without a good ground system, energy is lost, radiation is reduced, and signal efficiency drops significantly, even when the antenna itself is correctly installed and tuned.

The Monopole Mistake Killing Your SignalAdded:
You can have the perfect monopole antenna.
But if your ground is wrong, your signal won't go very far.
A monopole antenna is only half the antenna. The other half is the ground.
Think of it like this. The vertical element sends the signal out, and the ground completes the system. If the ground is poor, your antenna can't work properly.
Without a good ground, energy is lost, radiation is reduced, efficiency drops. So, even though your antenna is connected, it's not performing the way it should.
Here's what many people do. Mount a monopole with little or no ground plane, no radials, poor mounting surface, and then wonder why the signal is weak, or the range is limited.
What you want is a good ground plane. A good ground plane can be radials, and it can also be a metal surface.
Whichever you choose, it has to be a proper mounting structure.
The better the ground, the better your antenna performs.
Same antenna, same height, same power.
The antenna with a poor ground has a weak signal.
And the one with a good ground has a strong signal.
So, if your monopole isn't performing, don't just look at the antenna.
Look at the ground.
Because your antenna is only half the system.
