Sure, power strips are inexpensive. But they really only protect
against one type of power surge. If the voltage spikes, the breaker
should trip. However, this isn’t always instantaneous. Delicate devices
can still be damaged, and many other types of surges will just pass
right through without tripping the surge protector. Not the best
solution. Despite being called a surge protector, this name doesn’t give
you the whole story. These don’t even come close to the protection
whole house surge protectors offer you.
Additionally, many consumers overlook their most expensive possessions
when using power strips as a surge protector. Is your phone and laptop
always plugged in to a surge protector? What about appliances like your
stove, washer and dryer? A gnarly surge can also take these out! Most
of those are 240V, and you don’t often see a surge protector on those
outlets! Those things aren’t cheap! It’s estimated most households
have around $10,000 of unprotected electronics
<https://toronto.citynews.ca/2007/01/30/power-surges-can-fry-your-sensitive-electronics/>
with no surge protector. That’s a whole lot of money on the line! {pun
intended}
With a growing reliance on electronics and inevitable move towards smart
homes, it’s just not feasible to get a power strip for every single
outlet in your whole home. But, you can protect every electronic device
in your home with a small investment in a whole house surge protector
and a little elbow grease.
I strongly recommend and suggest one install a whole house surge
protector in or at the main breaker panel. Also careful
bonding of all ham station equipment is a must. And ALL outside
grounds must be bonded together and to the AC Mains
ground.

I posted a note yesterday that I took a power surge
That's probably because some part of your station was getting power from
a circuit that had an MOV "surge protector" in it, and your station was
not properly bonded. Study N0AX's ARRL book on the topic, to which I
contributed, and/or this slide deck for talks I've done on it.

MOV "surge protectors" are a common CAUSE of destructive failures.
