The Fracarro MAP313 is a three-input mast amplifier with a fully shielded metal chassis and F female connectors. It amplifies and mixes signals from separate VHF and UHF aerials, making it ideal for small and medium-sized terrestrial TV installations where antennas for different bands are mounted on the same mast.

Its innovative plastic housing locks the cover in place and allows the case to be rotated for easy alignment during installation. An adjustable plastic strap enables mast mounting on masts up to 60 mm in diameter. The unit requires an external power supply (PSU412 not included).

Key Features

• Three inputs: 1 × VHF (47–230 MHz) and 2 × UHF (470–862 MHz)
• VHF input gain: 24 dB; UHF input gain: 30 dB (each UHF input)
• Gain adjustment: 15 dB on all inputs
• Low noise figure: 5 dB (VHF), 8 dB (UHF)
• Maximum output level: 108 dBμV (IM3 -60 dBc, 3 tones); 115 dBμV (IM3 -35 dBc, 2 tones, DTT only)
• FM band on VHF input can be filtered via jumper
• Fully shielded metal chassis with F female connectors
• Adjustable plastic strap for mast mounting up to Ø 60 mm
• Supply voltage: 12 V; current consumption: 80 mA

Product Benefits

• Combining VHF and UHF signals at the mast reduces cable runs and avoids signal loss from passive splitters at the distribution point
• 15 dB gain adjustment on every input allows fine-tuning for installations where signal levels from different aerials are unequal
• FM filter jumper prevents FM radio signals from overloading the VHF amplifier stage in high-FM areas
• Full shielding minimises interference from nearby mobile or LTE signals
• Rotating case and strap mounting make single-person installation on a mast straightforward

Why You'll Love It

• Mast-mounting the amplifier right at the aerials maximises signal quality before it travels down the cable
• The rotating case and strap mean no special tools or brackets are needed for mast installation
• 30 dB UHF gain with a low noise figure is well-suited to areas with weak terrestrial digital signals
• The FM jumper filter saves you from having to add a separate FM trap in the signal path
