Solar activity (sunspots in particular), atmospheric conditions, distance, and geography between transmitters and receivers.
Propagative is the odd one out because it does not relate to relevance or importance, unlike the other words which allude to significance or derivation.
Propagative roots have plenty of reserve food and actively dividing meristems separated by permanent tissues. When broken into pieces, each piece develop into a separate plant using totipotency of plant cells.
The main problems of signal propagation include absorption, scattering, and reflection which can cause attenuation and signal degradation. Radio waves do not always follow a straight path due to factors like obstacles, atmospheric conditions, and interference, leading to signal loss and distortion. Reflection is useful in communication for extending coverage range through bouncing signals off surfaces, but it can also create multipath interference and echo effects, leading to signal distortion and quality degradation.
Signal interference, blocked signal, antenna problems or electrical faults.
There are many different kinds of suburban radio problems. These problems include but are not limited to shorting of the signal.

Noise signal is any signal which interferes with the main signal and does not give any important information.Signal should always be twice to that of noise.
