ChamTech's pronouncement is that existing antennas generate heat, which is wasted energy, though the presenter's association that they haven't evolved at all over the last 100 years is rather disingenuous. Radio antennas have evolved markedly, and there's still perpetual innovation in antenna design, even if much of it is conducted on a trial-and-error principle.
What is unclear from the presentation is how the size of the antenna is managed - radio aerials have a size common to the size (frequency) of the radio signal they are trying to receive (or fax). To pick up Radio 4 (at 94MHz) one should, ideally, have an antenna a shade over three metres desire. That's a little cumbersome, so we generally use fractions, and adjust the length of the antenna to pick up new frequencies.
But even if one has to measure the sprayed area accurately, the idea still has gigantic potential, and if used to cover an existing antenna the size is already consummate.
When applied to the antenna of an RFID tag (Seven minutes into the video) the coating evidently boosted the range from one-and-a-half meters to over 200m, and while applying a layer to antennas adapted to for undersea communications (which is very limited in range as radio doesn't remarkably penetrate water, even at 50MHz) it pushed the range from 30 meters to more than 1.6km (1 mile), which has gigantic implications for notoriously difficult submarine communications.
