LA380 vs. its predecessor LA350
With similar performances, the LA380 has following advantages:
-Wider frequency coverage (10kHz-500MHz), LA350 covering only 200kHz-30MHz.
-Full frequency coverage (10kHz-500MHz) with one single receiving element! LA350 needed 4 switchable
elements.
Directionality / reception pattern properties
A rotating loop antenna is very directional. The loop will allow signals on opposite sides to be received,
while off the sides of the loop the signal will decrease or be nulled out.
For example the nulling feature will allow you to remove a station on a frequency and pick up another
(transmitting from a different direction) on the same frequency. Of course the directional characteristics
when listening to distant sky-wave signals will not be as pronounced as local ground-wave propagation.
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).
