144 – 148 MHz Full Power 1500 W Ultimate Bias Tee – Remote Powering Outdoor
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 pre-amplifier and/or or transmit / receive relays via the coaxial cable. Like EME2-144, EME3-144 or Preamplifiers.
Main task is to inject DC current into, or extract DC current from coaxial cable, leaving the RF signal undisturbed. Bias tee is passive RF circuits consisting of a capacitors and inductor. Act as diplexer by combining DC and RF signals onto a common port RF+DC.
Antennas-Amplifiers “2m Bias Tee” has impressive RF performance on 2m 144-148 MHz and full power handling 1500 W.
Best in-class electrical performance:
|Frequency Range:||144 – 148 MHz|
|Max Power SWR 1:1||1500 W|
|Insertion loss:||0.015 dB|
|Input Return Loss:||-40 dB|
|Isolation RF port to DC port:||100 dB|
|DC resistance from DC to RF:||0.15 Ω|
|Supply Voltage:||30 V|
|Supply Current:||1 A|
Permanent damage may occur if any of these limits are exceeded.
Measured extreme high DC-RF isolation 100 dB that minimizes RF signal leakage and interference with other devices.
