- B.
7.000 - 7.035 MHz
- C.
Semua Benar
Correct Answer
C. Semua BenarExplanation
The correct answer is "Semua Benar" (All are correct). This means that all the given frequency ranges (3.500 - 3.900 MHz and 7.000 - 7.035 MHz) are part of the YD bandplan for the HF band.

Correct Answer
A. 144.000-148.000 MHzExplanation
The correct answer is 144.000-148.000 MHz. This is because the bandplan for VHF specifies that the frequency range allocated for this band is from 144.000 MHz to 148.000 MHz. Therefore, any frequency within this range can be used for VHF communication. The other options provided, 144.000-146.000 MHz and 142.000-149.000 MHz, do not fall within the specified bandplan for VHF.Rate this question:

- A.
50 cm
- B.
5 meter
- C.
50 meter
- D.
37,5 cm
Correct Answer
A. 50 cmExplanation
The wavelength of a wave is inversely proportional to its frequency. Given that the frequency is 150 mHz, which is a very low frequency, it can be inferred that the wavelength would be relatively long. Among the options given, 50 cm is the longest wavelength, making it the most suitable answer.Rate this question:

Yang termasuk dalam propagasi Ground Wave adalah:
- A.
Direct wave
- B.
Ground reflected wave
- C.
Surface wave
- D.
Semuanya benar
Correct Answer
D. Semuanya benarExplanation
Propagasi ground wave adalah jenis propagasi gelombang radio yang terjadi melalui permukaan bumi. Dalam propagasi ground wave, gelombang radio dapat merambat langsung ke penerima (direct wave), dipantulkan oleh permukaan bumi dan mencapai penerima melalui pantulan tersebut (ground reflected wave), serta merambat sepanjang permukaan bumi (surface wave). Oleh karena itu, semua pernyataan yang disebutkan dalam jawaban (direct wave, ground reflected wave, surface wave) adalah benar dalam konteks propagasi ground wave.Rate this question:

Correct Answer
A. Power Supply – Tranceiver – SWR – AntenaExplanation
The correct order of radio station setup is Power Supply – Transceiver – SWR – Antenna. The power supply is necessary to provide electricity to the system. The transceiver is responsible for transmitting and receiving signals. The SWR (Standing Wave Ratio) is used to measure the efficiency of the antenna system. Finally, the antenna is the device that sends and receives radio waves.Rate this question:
