LBNA2/LNNA2 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 420-1300 MHz band (bypass mode). It is possible to enable the integrated passband filter
(470-960 MHz) 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.

- White: when turning-on indicates the booster start up
- Yellow: booster bypassed, antenna becomes passive
- Green: active booster with gain between 1 ÷ 8 dB
- Blue: active booster with gain between 9 ÷ 15 dB
- Red: fast blinking, powering insufficient (lower than ≈
9,5Vdc)
3) + / - adjusting buttons
4) MENU/SAVE selection button allows to edit the following
parameters (after 5 second gain indication is restored by default).
