Optimal Antenna Connection
The Duo5800 was designed to be connected directly to the antenna’s RF connector with
as short a cable as possible, or ideally no cable at all.
Months of testing has shown that with this configuration, the best reception will be
obtained. You can even connect the Patch antenna directly to the Duo5800 (please be
careful not to put too much force on the SMA connectors if this mounting technique is
chosen)
Antenna Selection & Placement
The diversity receiver may be used with standard 5.8GHz antennas, equipped with a male
SMA connector. The spacing between the two antennas is not too critical on the 5.8GHz
band, even with two spiroNET antennas placed touching each other, multipathing effects
will be greatly reduced.
Frequencies
The Duo5800v4.1 RaceBand receiver has a dual-personality. In stock form, it behaves
similarly to it’s predecessors, the v1, and v2. The standard
‘ImmersionRC/FatShark/Airwave’ 7 channels are supported, and may be scrolled through
with the Channel button. The Band button switches between this band, and the new
RaceBand, shown in the table below..
