- DTM-40-7 CGLT7: antenna with active YAGI filter DIGI-YAGI 18U L7 (amplifier DIGI-YAGI 18U and YAGI LTE 700/800 LIGHT filter), tube reflector and »F« female connector
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.
Amplifier DIGI-YAGI 18U:
Frequency range: UHF Ch. 21-69 (470-862 MHz)
Amplification: 18 dB @ 5-24 VDC
P-P: 1,4 dB
Noise figure: 2 dB
Max. output level: 96 dBμV
Power supply: 25 mA @ 5-24 VDC
Connector: »F« female
YAGI LTE 700/800 LIGHT filter:
Filter passes all frequencies from 0 to 697 MHz (up to Ch.48) and primary cuts signals above 697 MHz (above Ch. 48).
Average attenuation of LTE 4G frequencies from 698 to 862 MHz (Ch. 49-69) is -20 dB.
Active YAGI LTE filter DIGI-YAGI 18U L7:
It is a single balun with combined amplifier DIGI-YAGI 18U and YAGI LTE 700/800 LIGHT filter.
