It’s easy, you just need a big antenna, low noise receiver (just cool it) for low bandwidth (keeps noise power low) and no interferers in the same frequency band.
That’s fair, though I think we also should thank the use of Travelling Wave Tubes (TWTs or ‘twits’). These little tubes of witchcraft amplify the transmission signal to make sure we can still hear, say, the Voyager 1 that’s currently over 15-billion miles away.
Omnidirectional antennas attempt to radiate equally horizontally. An isotropic antenna radiates equally in all directions but is only theoretical. All antennas have some gain.

Perfect. Now put those on cell phones and make it fit in your pocket.
Technology always gets better with no regard to physical limits.
(People who argue this unironically are a pet peeve of mine. Yes, there are limitations on what’s possible.)
Well until we get the space mushrooms
Then we’re un-liiiiiii-mited…together we’re unliiiimited
*directional antenna
Show me a non-directional antenna.
Omni-directional antennas?

Just because you call it non-directional doesn’t mean it is. They all have gain compared to a theoretical isotropic antenna.
Shrimple as that
It’s almost too easy
