LFA

Ultra-Wideband Active Antenna

with remote controlled filter bank

pg. 1

Horizontal Plane

120°

LFA is a wideband UHF antenna LPDA (log periodic dipole array) with integrated bandpass filter

and low noise booster.

It enhances reception providing approximatively 7dB gain with typical beam-width of 120

degrees. Thanks to an exclusive skeleton design with sloped elements, this antenna can work

in 410-1300 MHz band (bypass mode). It is possible to enable the integrated passband filter and

the internal booster (adjustable in 1 dB step).

The feeding line is integrated on the PCB (for mechanical robustness) and all the electronic and

mounting base are made by solid metal with waterproof gasketing.

ANTENNA PLACEMENT

Here above some examples of diversity antenna configurations.

In example 1 the antennas are side to side: although 20 cm (1 foot) it is enough for the diversity

to work, in this case it is advisable to keep them at least at 1 m (5 feet) distance in order not to

get them interfere each other. In the example 2 the antennas are mounted vertically in a more

convenient configuration (since they do not interfere much), this configuration is very good also

with 2 antennas used for transmission.
