ADFA
Ultra-Wideband Active Antenna
with remote controlled filter bank
pg. 1
ADFA
is an omnidirectional antenna with a unique design to achieve
an ultra-wideband of 430 -1160 MHz.
ADFA integrate a unique bank of filters along with a low noise
amplifier.
Filters and gain can be easily setup locally thru a 4 key navigation
buttons and a TFT display or remotely with a data connection on the
same RF coaxial cable.
Using the latest Wisycom filter technology, ADFA gives a full control of
RF zones and allows to build flexible and remote controllable antenna
systems.
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.
