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!)
What else can I help you with?
How far can a radio signal travel and what factors influence its range?
A radio signal can travel long distances, potentially thousands of miles. The range of a radio signal is influenced by factors such as frequency, power of the transmitter, antenna height, atmospheric conditions, and obstacles in the signal path.
When waves travel through a medium they carry the medium with them is this true or false?
False. Waves do not carry the medium with them as they travel through it. Instead, they transfer energy through the medium without permanently displacing the particles of the medium.
What basic law of electromagnetism explain how an antenna picks up a radio signal?
RF energy is transmitted through an electromagnetic field. Once the field meets the receiving antenna, voltages are produced by using the antenna as a conductor. RF voltages induced by the antenna are passed on to the receiver then reconverted to transmitted RF information.
what vcan travel with or without a medium?
Light is a form of electromagnetic radiation that can travel through a vacuum, or a space with no air, meaning it does not require a medium to travel through. Other forms of electromagnetic radiation, like radio waves, microwaves, and x-rays, can also travel through a vacuum. Sound, on the other hand, is a form of mechanical wave which requires a medium to travel. This medium can be a solid, liquid, or gas, and is the way sound travels from one place to another. For example, when someone speaks, the sound waves travel through the air and reach our ears. In summary, light and other forms of electromagnetic radiation can travel with or without a medium, while sound requires a medium to travel.
What factors should be considered when determining the appropriate antenna size for a wireless communication system?
When determining the appropriate antenna size for a wireless communication system, factors to consider include the frequency of the signal, the distance the signal needs to travel, the desired coverage area, and any obstacles that may interfere with the signal. Additionally, the antenna's gain, polarization, and radiation pattern should also be taken into account to ensure optimal performance.
What can travel through space without a(n) medium?
Electromagnetic waves can travel through space without a medium.
What is need of module?
we modulate audio signal due to following reasons: -audio is a low frequency signal that cannot travel longer distance due to low energy -if we transmit the signal without modulation then the height of antenna will be of the order of several thousand kilometers that is impractical

A radio signal can travel long distances, potentially thousands of miles. The range of a radio signal is influenced by factors such as frequency, power of the transmitter, antenna height, atmospheric conditions, and obstacles in the signal path.
Can light travel even without a medium?
Yes.
How far does a digital tv signal travel from a tower?
That truthfully depends on the transmitter's transmitting power, height of the transmitting antenna and the terrain.
When waves travel through a medium they carry the medium with them is this true or false?
False. Waves do not carry the medium with them as they travel through it. Instead, they transfer energy through the medium without permanently displacing the particles of the medium.
What kind of wave can travel without any medium?
Electromagnetic

What is a wave without a medium?
A wave without a medium is an electromagnetic wave, such as light or radio waves, which can travel through a vacuum because they do not require a material medium for propagation.
Sounds need these in order to travel?
Sounds need a medium to travel, such as air, water, or solid materials. As sound waves pass through the medium, they cause particles to vibrate, transmitting the sound energy from one point to another. Without a medium, such as in a vacuum, sound waves cannot travel.
