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!)

Can light be transmitted with or without a medium?
Light can travel with and without a medium.
Can electromagnetic waves travel without a medium?
They do not need a medium.
Sound needs a medium for traveling?
Sound waves cannot travel without a medium. Therefore, any big explosions in space cannot be heard. Light waves can travel without a medium.
Can a tranverse wave propogate without a medium?
light travels as a transverse wave and it can travel without any medium as it does while travelling in space.
How does energy transfer without a medium in a wave?
The only way energy can travel without a medium is by electromagnetic waves, or in other words, photons.
Can light be transmitted with or without a medium?
Light can travel with and without a medium.
What can travel through space without a(n) medium?
Electromagnetic waves can travel through space without a medium.
Can electromagnetic waves travel without a medium?
They do not need 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
Sound needs a medium for traveling?
Sound waves cannot travel without a medium. Therefore, any big explosions in space cannot be heard. Light waves can travel without a medium.
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.
What kind of wave can travel without any medium?
Electromagnetic
Can a tranverse wave propogate without a medium?
light travels as a transverse wave and it can travel without any medium as it does while travelling in space.
How does energy transfer without a medium in a wave?
The only way energy can travel without a medium is by electromagnetic waves, or in other words, photons.
What type of wave requires no medium to travel through?
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
What can travel though space without a medium?
Light, radiation, radio waves.
