Just what do they mean by Active? (hey,I am dumb) Does it mean it is
Active because they use a battery and the battery "Activates" it?

And active antenna is an antenna with a built in amplifier, or "active"

component. For example the AmRad active antenna uses a special
FET (Field Effect Transistor) and is "as effective" as a ~100' long
wire.

For low frequencies, like a 60KHz signal, even a 100' antenna is short.
The AmRad, DA100-E, "North County" and even the "Tiny Tenna"
all use transistors to convert a small 36" or so, wire into a usefull
antenna. The Tiny Tenna is the simplest, but even it will do a decent
job far from any MW (AM 540~1600KHz).

Loops can be passive or have amplifiers, and those with amplifiers
are termed active.

For RF reception from 500KHz through ~30MHz I prefer the common
~100' wire antenna. For MW DX work a loop is hard to beat. For
LF work, 500KHz and lower, an active antenna is the only practical
way to go.

Awwwww, forget them Tiny Tunna,s (Oooops,Tiny Tenna's) I bought one of
them from that fool about eight years ago.It arrived here dead on
arrival,I will never buy anything from that mf (Massey Ferguson) b.....d
ever again.Thanks anyway for the explaination about active antennas.
