Used to have aluminum foil flags on the rabbit ears TV antenna. Worked a dream, some days could get Cheyenne and Denver!

@drmuso I believe you. :)

I only meant that with mesh networks the overall need for aluminum foil tweaks goes down.

I think the article is correct for the physics. I just think most consumers would opt for moving the router or using a mesh network to extend it first.

There is of course the benefit that shaping your wifi footprint away from neighbors and the street can make it harder for crackers to drive by and hack into your network.

You said to have fun…I tried. 

The Firewalla Purple does an excellent job at keeping your network private. 
 

Mesh networks: WiFi 6 or WiFi 6e? What are you using for the backhaul? If you put in a mesh network, know what to buy, and how to set it up. There is more to it than unboxing the nodes and turning them on.
