RF extension cables, also know as pigtails, are ideal to connect your radio module to an external antenna.
Connector: SMA Male - N Male
Length: 1000mm (1 meter)
Cable Type: RG58
Impedance: 50 Ohms ± 3
- 0.2 @ 100MHz for RG58
- 0.8 @ 1GHz for RG58
To minimize any signal loss, you should use the shortest cable possible and minimize the number of connections between the radio module and antenna.
