Iam an electronics n communication engineer..people have misunderstood the concept wrongly...low frequency signals have larger wavelength ..so it's vibration is less so it is easily not disturbed ...it can travel...

Abhishek RawalE = hf Which means Energy is directly proportional to frequency. Low frequency have low energy, so less distance traveled & thus HF can travel long distance. Correct me...

Frequency actually has various characteristics ..for sky wave n ground wave..in general high frequency has lower wave length so it disturbed due to more vibration...but low frequency has greater wavelength...
