Smallest that would fit a battery and a Heltec v4.
Live in a fairly small town in the southeast US but the local Amateur Radio club has a Meshtastic radio on a tall building in town and I was immediately able to see ~20 nodes and had 5 people talking in LongFast.
Wish I could have an outdoor pole mounted base station, but living in an apartment makes it hard. It seems to work okay on my 3rd floor windowsill though!

You lucky sod! In Toronto we had someone install a node on CN Tower. It was a miracle. We talking from one end of GTA to the other, a 50km span, became 1-2 hops, down from 5-6. And then two days later it disappeared. The person who installed it disappeared from the Discord. Accounts deleted. No further communication. I assume something went wrong with his employer and whoever manages the CN Tower radio installations.
Bummer! But I’m talking like 50ft here lol not CN tower. That thing is insane, I’ve been up there.
