The TW155 by Tallysman Wireless is a professional grade wideband Bias-Tee for injecting DC voltages onto coaxial lines.
The regulated output voltage and the large output current makes this product highly suitable for many active antennas
and amplifiers. It is useable up to 6GHz with higher insertion loss (see data below).
The TW155 is housed in a robust RF sealed, weatherproof (IP67) clear anodized aluminum enclosure and is available with 3 x SMA or TNC Jack connectors.
