1.5 V, up to 1 A… That’s very little power, barely enough for a preamplifier.
I’m confused as to what this was used for. There are AM travelers’ information stations at 1610 kHz in the US so the unit would be installed in a vehicle but then it is no problem to use a separate power cable or a 3-wire one because it’s just a few meters at most. And the frequency is within the MW band so it can be received by any car’s radio anyway, no need for a separate device.
Edit: It says “1-60 MHz”, not “1.60 MHz”, which I couldn’t make out because of the low resolution. That makes it way more versatile.
I have seen Bias Tee injectors for up to 50v@1.5A, thats enough for a decent output booster. But yes in reality 99% of those where used for preamps in analog TV/Radio Rx
It also says 1-50vdc not 1.50vdc, so 50 watts of power at 1amp
Some antennas have active components (not just preamps) that require some kind of DC voltage to work properly. Pretty common in dedicated GPS antennas. They also have bias ts covering pretty much any band you can think of. Well into the GHz range.
Damn, I love path of exile
The Picosecond Pulse Labs bias tees hold a special place in my heart.
