This line amplifier has a minimum gain of 20 dB with one input and one output in a miniature housing. The frequency response covers both L1/L2 and Glonass bands with excellent gain flatness. In normal configuration, the RF output (J1) passes DC from the connected GPS receiver through the amplifier to the antenna, allowing the GPS receiver to power both the antenna and the amplifier.
This mini line amplifier (Alternate Part# MLA20 RDCBT) has TNC connectors.
