Product Description
High Gain (27dB) UHF Masthead Amplifier for 1 TV
Do you have problems with poor TV signal, and wondered how to boost reception?
Our high performance, masthead amplifiers are ideal for boosting your UHF TV signal. They are extremely low-noise (reduced interference) offering better signal quality.
How do I install my UHF amplifier?
Masthead amplifiers are installed externally in a robust weather-proof casing, which slides up to reveal the amplifier. This is typically installed on the aerial pole.
It also requires a power supply which can be bought separately or as a kit. The power supply is installed behind one of the TVs in the system. Simply install the power supply inline with the cable and plug it in to a mains socket. It then sends power up the cable to the masthead amplifier. This is ideal if you cannot install a distribution amplifier in the loft due to lack of a mains socket. Please note: any 5-12V source can be used instead of a power supply.
Features:
- Fully-screened masthead amplifiers with 'F' connector (screw on) outputs. Which means less interference caused by passing vehicles or other strong signals the F connectors ensure the lowest loss on a weak signal and screw on for a secure connection.
- Low noise figures and well-filtered inputs. Low noise figures help because on a weak signal you already have lots of noise and the last thing you want an amplifier to do is add more noise to it.
- Sharp cut off below 400MHz, helps avoid interference problems from nearby transmitters: CB, PMR, TETRA, HF and VHF amateur radio, etc.
- Variable gain models have inter-stage control to maintain good noise figure at reduced gain. Variable gain means you can adjust the amount of amplification required to either boost your signal.
- With equipotential bonding point. This is to allow you to earth the amplifier and help discharge static electricity.
Technical Information:
Product Code | Ways | *Gain | *Noise Figure | *Max Input | *Power Requirement | Typical Applications |
PROMHD11L | 1 | 9dB | 1.8dB | 80dBV | 5 - 12V, 25 mA | Margin raising preamplifier |
PROMHD11M | 1 | 16dB | 1.7dB | 75dBV | 5 - 12V, 25 mA | For weaker signal areas |
PROMHD11H | 1 | 27dB | 1.8dB | 74dBV | 12V, 50 mA | Long downleads, splitters |
*Gain: This is the amount of amplification the amplifier can provide and the higher the number the more it will boost your signal.
*Noise figure: Low noise figures help because on a weak signal you already have lots of noise and the last thing you want an amplifier to do is add more noise to it.
*Max Input: The maximum amount of signal the amplifier can safely handle on the input from the transmitter/aerial.
*Power requirement: The power supply’s required voltage and ampage to drive the amplifier.
The maximum output level per multiplex is per the table in dBV when there are eight equal level multiplexes. If the number of multiplexes to be carried is not eight please refer to our Mux guide.

Does the job - excellent.

Response from Blake UK in every respect was very good and the product purchased is excellent. My only criticism is that the package that my omni FM/Dab aerial was sent in could have had more packing material as the carton was damaged in transit with a part of the product sticking out.

FM Roof Aerial Kit This Blake UK FM Aerial Kit is of excellent quality. Noticeably better in every way than another two kits I've had over the last 15 years from other sites, lower cost and with lower shipping costs. Will definitely buy from them again.
