| The LA380 is a compact active (30cm diameter) loop
aerial specifically designed to provide good reception when away from the main monitoring location or when
large external aerials are not practical.
Compact, but achieving high performance, featuring an internal
high gain amplifier (20dB for 10kHz-250MHz) and excellent overall strong signal handling (high IP3
+10dBm).
The rotating loop element provides excellent directivity
in peaking and nulling signals (ideal for minimizing the effects of unwanted interfering local terrestrial signal
and noise), of course the directional characteristics when listening to distant sky-wave signals will not be
as pronounced as local ground-wave propagation.
The loop element features a 5 positions band switch
and a High-Q poly-variable capacitor to tune and peak the wanted frequency, while achieving maximum
rejection of unwanted out of band signals / valuable additional selectivity for your
receiver's front-end stages. |
