The Jolly Line 45982 is a multiband TV amplifier intended for central antenna system installations. It accepts four independent signal inputs — VHF, Band IV, Band V, and UHF — and delivers two outputs, one of which is a test output for monitoring. A built-in 5G filter covering 694–862 MHz suppresses out-of-band interference from 5G networks.

The amplifier offers front-panel gain controls on all four bands, keeping the output level consistent across different signal environments while maintaining low power consumption of 7 W. It supports both digital and analogue terrestrial channels across all supported bands.

Key Features

Product Benefits

• Independent gain controls per band allow signal level equalisation across VHF, Band IV, Band V, and UHF without external attenuators
• The built-in 5G filter (20 dB) and 4G filter eliminate interference from mobile networks, protecting reception quality after spectrum reallocation
• The test output allows signal level monitoring during commissioning or fault diagnosis without disconnecting the main distribution feed
• Low 7 W power consumption reduces operating costs in always-on central antenna systems
• The wide power supply range (90–250Vac) makes the unit compatible with different mains standards

Why You'll Love It

• The test output means you can check signal levels at the amplifier during installation or maintenance without interrupting service to the distribution network
• Front-panel controls are accessible without opening the unit or using a laptop, speeding up on-site level adjustment
• The dual 5G and 4G filtering protects installations against interference in markets where both frequency bands have been reallocated to mobile operators
• At only 7 W the amplifier can run continuously without significant contribution to energy costs in a central equipment room
