Question

Advantage of HF transmission is
A) that the length of antenna is small
B) that the antenna can be mounted at larger heights
C) that the power radiated is more for a given length of antenna

• A. a & b
• B. b & c
• C. a & c
• D. a,b & c

Answer 1

Answer: (D)

a,b & c

The main advantage of higher frequencies is that they require shorter antennas for decent reception quality, and that's important for mobile devices. They also allow a wider band for modulating signals, so you can obtain higher frequency transmission.
