This an RF load unit to terminate a transmitter antenna connection for use while testing and when changing channels in an area where you could interfere with other people on nearby frequencies. This will also protect the VTx from accidental power up that can cause damage.
SMA male RF load has 50 Ohm impedance and is rated for a 0-18GHz . Dummy load / RF termination has a maximum input power of 1 Watt and a maximum VSWR of 1.15:1.
Termination Type: RF Load Connector Series: SMA Connector Gender: Male Minimum Frequency: DC Maximum Frequency: 0-18GHz Impedance: 50 Ohm Maximum Power: 1 Watt
