The 1851 series cable is a coaxial cable
for wireless antenna connection, using an
RP-SMA (reverse polarity) male connector on
one end and an RP-SMA (reverse polarity)
female connector on the other end. This
cable is used as an extension for SMA
reverse polarity wireless antennas.
Most PCI wireless cards, including the
and EW-100G, use SMA
reverse polarity connections to their
antennas. This cable can be used to
place the antenna away from the computer.
This cable is made with RG-58 coaxial
wire, having a nominal impedance of 50 Ohms.
We can also build this cable in any length you request.
Please note that this cable is of Reverse Polarity, meaning that
the male outer-locking connector has a jack and the femal inner-locking
connector has a pin. RP-SMA is most common on consumer-targeted wireless
electronics. If you need a standard polarity cable, with outer-threading
and the pin both on the male end, see our SMA Extension Cable.
