The short answer is "by superheterodyning it". A more complete answer requires information not given in your question.
Microwave Radio Frequencies (RF) does not travel through dense metals. A metal roof would block the signal. If you try to get your position on a GPS inside the temple and cannot, then the satellite signals are blocked.
A portable handheld radio receiver operating in the microwave band, that when it detects microwave RF above a certain strength it gives some form of warning signal. This warning may be audible, visual, or be shown on the face of a meter.
A; BUFFER is used for isolation, translation of levels and amplification if needed
AF modulator. Audio signals produced by the microphone get amplified enough with the power to modulate the RF carrier wave generated by a RF oscillator.
RF is short for Right Fielder. In the context of the category where this question was posted, RF probably refers to "radio frequency". "Radio frequency" usually refers to a rate of oscillation in the range of about 30 kHz (30,000 cycles per second) to 300 GHz (300,000,000,000 cycles per second). This is the range of frequencies of electromagnetic signals we call radio waves. Although RF usually refers to electrical rather than mechanical oscillations, mechanical oscillations in this range can also be referred to as "RF" (that use is a bit obscure though).

A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
An RF signal travels at the speed of light in space, which is approximately 299,792 kilometers per second. This means that RF signals travel at the same speed as light in a vacuum.
Yes. An antenna is only used to receive or send a signal. A RF signal travels throughout any air medium independently of the existence or not of an antenna. Of course you will need an antenna if you want to receive the signal (which has to have, by the way, more or less the same lenght of the wavelength of the RF signal), but the propagation of a electromagnetic wave doesn't need a physical support. You can see an example with the radiotelescopes. They receive signals which come from the outer space without any physical support. Electromagnetic waves (and RF signal is one kind of them) doesn't need any physical media to travel (they travel in vacuum too!)

Television signals are transmitted on a high frequency (or RF) carrier signal. The technique of adding the signal to the carrier signal is called modulation. This happens for all radio transmissions. A VCR that has a modulator allows the output signal to be turned into an RF signal. The signal is added to the RF signals that are fed into the VCR via the aerial feed. Although it is rarely needed today, older televisions often had no video or audio input so the VCR output could be sent to the television as RF to allow the tuner to capture and display the signal. Most VCR modulators have a control to adjust the carrier frequency to allow it to use a channel that is not use by other broadcast television signals. Modulators are used less often in recorders and players as virtually all televisions have at least one video input.
The polarity of radio frequency (RF) signals in antenna design is important because it affects how well the antenna can transmit and receive signals. Matching the polarity of the antenna with the incoming signal helps maximize signal strength and clarity. When the polarities are aligned, signal transmission and reception are more efficient, resulting in better communication. Conversely, mismatched polarities can lead to signal loss and reduced performance.
Yes, a radio transmitter converts an electronic signal (such as audio from a microphone) into radio frequency (RF) waves. These RF waves are then transmitted through antennas as electromagnetic radiation, which can be converted back into sound waves by a receiver like a radio or smartphone.

RF direction finders use antennas to receive radio frequency signals from a transmitter. By comparing signal strength or phase differences at multiple antenna locations, the direction to the transmitter can be determined. This information helps locate the source of a radio signal.

The size of an antenna depends upon the frequecny of the RF signal and the gain.
