Solution:

It is allowed to add an extra cable between ADAM-4550 and antenna. There are some examples for your reference: As you know: ADAM-4550-A: SMA connector with male type ADAM-4550-B: SMA connector with female type ANT-6010: SMA female to N male ( for ADAM-4550-A ) ANT-6011: SMA male to N male ( for ADAM-4550-B ) So possible connection diagram are shown as below: 4550-A <=> ANT-6010 <=> antenna with N female 4550-A <=> ANT-6010 <=> ANT-6030 ( or ANT-6022 ) <=> antenna with N male 4550-B <=> ANT-6011 <=> antenna with N female 4550-B <=> ANT-6011 <=> ANT-6030 ( or ANT-6022 ) <=> antenna with N male The following detailed information is for your reference: ANT-1208 8 dB omni-directional antenna ANT-1212 12 dB omni-directional antenna ANT-1224 24 dB parabolic reflector antenna ANT-6010 2ft RF cable SMA standard to N male ( for ADAM-4550-A ) ANT-6011 2ft RF cable SMA reverse to N male ( for ADAM-4550-B) ANT-6021 20ft RF cable N female to N male ANT-6022 20ft RF cable N female to N female ANT-6023 20ft RF cable N male to N male ANT-6030 Lightning Arrester ( N female to N female )
