They've got it there - the length and shape of an antenna determines which frequencies it is most happy to transmit and receive - based on a formula of the wavelength and the harmonics of the antenna.

So air pressure applied = amount of liquid metal in tube = length of antenna element = frequency amplification/attenuation.

A liquid antenna has some the same advantages of a gaseous or plasma antenna. That is, it takes the shape of it's container. Need a disc-shaped antenna? Pour it into a disc-shaped container. Need a wire antenna? Pour it into a piece of tubing. Need a ring-shaped antenna? Bend the tubing into a circle. etc. etc. etc. Need less or more antenna? Remove or add fluid. Of course it has disadvantages. One being that bubbles can become breaks in the circuit.
