Cool Old SWR/Power Meter


Nothing really exciting. I have half a dozen of them, with and without the little wire antenna for field strength. Very little accuracy as a wattmeter, but will give a decent RELATIVE reading for reflected power. These don't measure "SWR"; they measure reflected power. The readings require you to squint and accept the manufacturer's assumptions.
 
I have 5 or 6 old CB SWR bridges too of different makes and styles. .Not even sure where they all came from. Probably followed me home from a swap meet "free box"
One like that, as was mentioned, probably cost around $12 to $15 back in the early 70's.

Okay now I'm completely confused, which is certainly not a rarity. I thought an SWR measurement WAS a measurement of reflected power.

They are different.
SWR is the ratio of the antenna's impedance versus the transmission line impedance I believe. Reflected power is part of that equation. The meter you have will indicate both.
