Hello,
At this adress:
http://www.lesaunier.com/htm/franklin1_eng.htmi put an explication to build an
Franklin antenna (4.5 dB) for the RB.
my apologies for the bad "english".i will send some screenshot of the maximum range with this antenna.
Actually, the antenna i not on the right position (for test), and i have
a good reception up to 150 mn on the south (with peak to 180 mn) and
without amplifier and 5m cable.
On the north, is less well because the antenna is not optical free !!!
(not better than 80 mn)
