What’s a Bias Tee?

A “Bias-Tee” also known as a “DC Inserter” is a simple way to feed DC power through coaxial cable to the remote device such as a pre-amplifier and/or or transmit/receive relays via the coaxial cable.
Like EME2-432, EME3-432, or Preamplifiers.

The main task is to inject DC into or extract DC from the coaxial cable, leaving the RF signal undisturbed.

A bias tee is a passive RF circuit consisting of capacitors and inductors. Act as a diplexer by combining DC and RF signals onto a common port RF+DC.

Antennas-Amplifiers “70cm Bias Tee” has impressive RF performance on the whole 70 cm band 430-450MHz or full range 400-500MHz and high power handling 1200 W.
