This bias tee box is used to insert DC power into an HF signal to power remote antenna amplifiers or other devices. It is usually positioned at the receiving end of the coaxial cable to pass DC power from an external source to the coaxial cable running to powered device. A bias tee consists of a feed inductor to deliver DC to a connector on the device side and a blocking capacitor to keep DC from passing through to the receiver. Bias tees are used in a variety of applications, but are generally used to provide an RF signal and (DC) power to a remote device where running two separate cables would not be advantageous.
Using
- Providing an RF signal and (DC) power to a remote device over one coax
- You can use bias tee on both sides as DC IN and OUT from RF coax
- For preamplifier or Bi-dir beverage
Main functions
- Broadband: 0.1 MHz to 60 MHz
- High Pass Filter 100 kHz (AC noise filter)
- Variable ATTENUATOR - settings
- Front-end protection with diodes - settings
- DC short protection about 1A7
- Power supply common-mode filter
- High voltage and current protections
- LED diode indication of DC power on the coax
- You can set ATT when you have too high gain of preamp
- Quality connectors
- IP56 box - recommended to protect it against water
- Feeder size 100x100 mm
- ASSEMBLED AND TESTED VERSION
Parameters
- Supply voltage DC up to 24 V
- HPF 100 kHz ( > 40 dB @ 25 kHz)

- High RF voltage and current protection (90 V, 200 mA)
- Supply current up to 500 mA
- Insertion loss lower than 1 dB - for minimal ATT
