A bias tee that combines DC and RF on one coaxial line from 10 MHz to 10 GHz. Feed up to 50 V and 400 mA through the DC terminal to power an LNA, active GPS antenna or remote module over the same cable that carries the signal.

Questions
Which port goes to the antenna or LNA?
The RF + DC port. The RF port goes to your receiver or instrument and carries no DC.
Can I power a GPS antenna with it?
Yes, if the antenna takes its supply over the coax: set your supply to the antenna's voltage, within 50 V and 400 mA.
Is insertion loss specified?
The maker's datasheet gives frequency, voltage and current only. Ask us if you need test data.
