LA-390 Antena Loop Aerial 10kHz ~ 500MHz  


 

 

The LA390 is a high performance active aerial loop, ideally suited for internal or desk top use where larger external aerials are not possible. The single loop is Approximately 30.5cm across with 5 selectable bands having excellent directivity is nulling interference. The aerial is powered from 12V (power supply provided) and comes complete with a 1 meter BNC to BNC coax lead.

• Directivity

The rotating loop antenna is very directional. Depending on the loop's orientation, you can peak an incoming signal depending on its direction, or decrease an interfering signal. For example the nulling feature will allow you to remove the station on the 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 the pronounced the ground-wave propagation site. Thanks to its directivity, it is Also ideal for Minimizing the effects of unwanted place interfering terrestrial signals and noise

• Band switch selection

The loop has 5 switchable bands making it not only an excellent HF aerial but Also makes it a highly practical solution for wider band receivers working up to UHF frequencies.

• LA390 vs. LA380

With similar performances, the LA390 offers in addition preselection for L.W and M. W bands, but not for the 40kHz and 60kHz signals team. Preselection sharpness has Also be improved.
