LIRA-433, on-site targeted antenna 433 МHz, +11 dBd

Is designed for greater distance range and better communication from on-site transmitters in REEF String RS-202, REEF String RS-200 and REEF String-701 systems as well as between all other transmitters and receivers operating in the 433 MHz frequency band.

Original patented design of the symmetry device contains a band filter, which well adjusts antenna to the cable only within the operating range, reduces noise level at the output and provides secure lightening protection for connected equipment.

 

All electrical characteristics are highly durable even in a severe climate due to transponder and symmetry device design from anodized aluminum as well as to the lack of direct contact between the transponder and the central cable wire (al.-copper)
