Fully screened Mast Head Amp with inter-stage variable gain. The amp will not pass FM/DAB, if required this should be diplexed in after the amplifier. The amp can supply one TV point directly or a number via a splitter with power pass. As an example, if the amp were turned up to 22dB and then sent through an 8 Way splitter (with a through loss of 12dB) you would still have a “nett gain” of 10dB per output, less any cable loss. The weatherproof enclosure makes it equally suitable for mounting on the aerial mast, or on the wall, or in the loft. The plastic housing is removable, if required, so the amp unit can be screwed directly to any surface, e.g a loft joist. The amp is not cascadable, which is usually a good thing……
Max recommended distance from the PSU to amp would be well over 250m, though that is purely theoretical because the signal (travelling in the opposite direction) would never get as far as that, not in a usable form anyway.
Earth bonding terminal.
Gain = Variable (interstage) : 1 x 7 to 22 dB
Max input level = 80 dBμV
Noise = 2.5 dB
Power requirement = 12V x 50mA
Power Supply (if required, available separately)
Output Voltage = 12V (+/- 0.6V) x 100mA
Insertion loss = Less than 0.5 dB
Protection = Short circuit (indefinite)
Power consumption = 240V x 3W

2 year warranty on this product.
The 4 F connectors required are included in the price, and they`re decent ones !

The system below includes a tap and a splitter, but use of just splitter(s) is probably more common !
