YAGI LTE filters (passive components), amplifiers DIGI-YAGI (active components) or Active YAGI LTE filter (active components) are made as s single balun. They can be installed only into YAGI antennas with DTX dipole (into all DTX, DTM, TRIPLEX and UF antennas).
They have »F« female connector and can be used for upgrading existing antenna too. For replacing balun (upgrading) the tools are required.
Antenna with built-in amplifier DIGI-YAGI or Active YAGI LTE filter is receiving signals only if amplifier is power supplied. It can be supplied from outside power supply of directly from DVB-T receiver. Power supply is provided through the same coax. cable as reception signal.
