Fracarro MAP4RU LTE700+K (223718) Masth Amplifier Digital TV Antenna Booster 42dB, 4G/5G/LTE Filter | By JJSATs

Product Overview:
The Fracarro MAP4rU LTE700+K Mast Amplifier Kit (Product Code: 223718) is a terrestrial digital TV (DVB-T2) UHF masthead amplifier kit featuring an exceptionally high gain of 42 dB. It comes complete with a power supply unit (PSU) included in the package. This device is designed to resolve weak source signals or compensate for signal loss (drop) over long cable runs, ensuring the signal is strong enough to travel extended distances without degradation. It serves as a core component for receiving Free-to-Air (FTA) TV signals for distribution across small to large-scale centralized TV networks, including MATV, SMATV, IPTV, and Hotel IPTV systems. It is perfectly suited for installation alongside digital TV antennas in hotels, resorts, condominiums, apartments, dormitories, government buildings, corporate offices, and residential homes to stably deliver crystal-clear signals to multiple users or viewing points.
The MAP4rU LTE700+K mast amplifier stands out with Fracarro's exclusive CLIPPER Technology, which automatically limits the UHF band gain to guarantee the maximum available RF output level while minimizing intermodulation. Furthermore, it features an integrated 5G and 4G LTE filter that effectively blocks interfering cellular signals at frequencies from 694 MHz and above. This makes it highly suitable for use with digital TV antennas, especially older models lacking built-in mobile network filters. For optimal amplification performance and the best possible signal quality, it is highly recommended to install the amplifier as close to the antenna as possible.

Ideal Applications:
- Centralized TV System Main Amplifier (MATV/SMATV): Serves as the primary booster to amplify terrestrial digital TV (DVB-T2) signals for distribution throughout multi-dwelling units and complexes.
- Headend Signal Optimizer for IPTV / Hotel IPTV: Ideal for stabilizing and boosting Free-to-Air (FTA) signals from the antenna array before feeding them into IPTV streamers or encoders.
- Long-Distance Signal Drop Compensator: Perfectly suited for large residential properties or commercial buildings to offset severe signal attenuation caused by extended cable runs and high splitter counts.
- 5G/4G LTE Interference Shield: Highly recommended for installation alongside standard or legacy digital TV antennas located in high-density cellular areas, effectively preventing mobile network spikes from disrupting TV reception.

Key Features:

1. Exclusive CLIPPER Technology: Fracarro's unique built-in system that intelligently limits the maximum gain of the UHF band. This guarantees the absolute maximum available RF output level while successfully minimizing intermodulation distortion. A dedicated onboard LED lights up whenever this automatic threshold control is active.

2. Integrated 694MHz 5G & 4G LTE Filter: Features a built-in cellular filter tuned precisely to suppress network signals above 694 MHz, shielding the digital television band from aggressive mobile data transmission spikes.

3. High-Shielding ZAMA Die-cast Frame (LTE Free): Configured with an internal ZAMA zinc-alloy die-cast frame and metal backplates. This provides superior RF isolation against localized noise and external electromagnetic interference.

4. ABS Outdoor Protective Hood with Tilting Mechanism: The weatherproof ABS plastic outer casing is equipped with a functional slide-opening and tilting assembly for the core circuit block. This arrangement gives installers unobstructed access during tower wiring and physical alignment.

5. Remote Tele-power Switch & Status LED: Incorporates a mechanical selector switch allowing users to push remote tele-power backward to the UHF input port when active components are attached up-line. Includes a visual LED indicator to confirm safe power delivery.
