Labgear UHF Variable Mastheads
PUH141 + PSM114V: UHF 470-862 MHz 4-way 12-16 dB comes with PSM114V
PUH111 + PSM114V: UHF 470-862 MHz 4-way 16-24 dB comes with PSM114V
These new technically advanced UHF antenna preamplifiers offer unparalleled combination of low noise, good input filtering and high output
capability. The amplifier units consist of fully screened, sealed modules fitted with Type-f connectors. These preamplifiers come with a moulded
ABS weatherproofing enclosure for outdoor applications.
Features and Benefits
System can be commissioned in side the house by adjusting the variable power supply to optimise signal level
•
Industry-leading noise performance
•
Inputs well filtered below 470 MHZ to minimise interference from Tetra transmissions
•
Ideal for both Analogue and digital (DTT) applications.
•
Indoor or outdoor use
•
The PUH141 can be powered via any of its outputs and signal levels can be optimised by adjusting the unique PSM114V to set the levels
•
without the need to go outside.
PUH111 + PSM114V- high gain 16-24 dB variable gain masthead kit.
The PUH111 Kit enables you to stock one product for 3 applications; it is suitable for DTT applications where the off air signals need to be lifted
by a minimal amount. This unique method allows you vary the voltage which in turn adjusts the gain of the amplifier. Where more gain is required
leave the power supply at the factory setting to give you maximum gain. Examples are very long cable runs, with remotely mounted antennas;
Receiving extremely weak signals in badly screened locations
•
Small distribution systems using passive taps after the preamplifier.
•
Comes with PSM114V to optimise required signal in side the house
•
PUH141- UHF 470-862 MHz 12-16dB 4- way distribution amplifier comes with PSM114V
The PUH141 provides a fully DTT-compatible solution for feeding several TV points from one antenna. The wiring can be mainly on the outside
of the building, making this a popular solution for the retro fit on older buildings, now with more gain it lends its self to be used in weaker signal
areas and signal can be optimised by the PSM114V. The PUH141 can be powered from any output making installation even easier.
Notes
These amplifiers have a maximum input capability of around 75dBµV (for 5 analogue TV channels with 6 lower-level DTT multiplexes). If signal
levels exceed this figure it is unlikely that a preamplifier would be required.
Masthead preamplifiers should never be used as a substitute for an adequate antenna, although they can reduce the antenna size required in many
cases. A preamplifier will not cure problems caused by co-channel interference or multi-path propagation (ghosting), both of which may point the
need for a more directional antenna.
