When considering buying an amp (or “booster”), remember the basic rules :
A splitter (if it`s possible to use one) is preferable to an amp.
In the case of poor signal (to one point), Aerial First, Then Amplifier !
Two way screened weatherproof external splitter. This unit may be mounted on the aerial
pole or on the wall. Loss 3.5dB. Through power (for a M/H amp, if required) on leg two.
Saddle and clamp for most secure connection of the cable(s). See article on Splitters.
Four way screened weatherproof external splitter. This unit may be mounted on the aerial
pole or on the wall. Loss 7.5dB. Through power (for a M/H amp, if required) on leg one.
Saddle and clamp for most secure connection of the cable(s). See article on Splitters.
All our splitters are metal (not crappy plastic.....)
which not only makes them more robust but it
also means they`re screened. All the F connector splitters have power pass on any
leg, the Co-
Any F connectors required with our splitters (or amps) are included in the price,
and they`re decent ones !
Through loss on splitters :
2 Way = 4dB
4 Way = 8dB
6 Way = 10dB
8 Way = 12dB
See article on Splitters.
Our Two Way Mains Amps are variable gain. They are equally suitable for just one TV but obviously give you the flexibility to supply a second set if required.
They are definitely screened as the above right picture proves !
Gain can be varied (2 x 7dB to 17dB) and the noise figure is 4dB
Input frequency 47 to 862MHz which covers the FM, DAB and TV bands.
See article on Mains Amps
These Four Way Mains Amps (equally suitable for running two or three TVs) provide
4 x 8dB outputs, with a noise figure of 4dB, and have 12V line power for a mast head amp.
They are definitely screened as the above picture proves !
The amps have separate inputs for TV (470 to 862Mhz) + FM and DAB (88 to 862Mhz).
If a suitable FM/DAB aerial is connected to the second input, each of the outputs can
then supply a TV and /or an FM or DAB tuner, either via a 2 way splitter or better still
via a “Set Back Diplexer”. See article on Mains Amps
These Six Way Mains Amps (equally suitable for running two to five TVs) provide
6 x 8dB outputs, with a noise figure of 4dB, and have 12V line power for a mast head amp.
In addition they have a “Full” output of 18dB which can be used in conjunction with
a splitter to supply more points. As an example, if a 6 way splitter was used (which
has a through loss of 10dB) one would still have 8dB (18 -

Fully screened Mast Head Amp with variable gain (7 to 22dB) and a noise figure of 2.5dB.
The maximum input level is 80dBuV and the unit amplifies frequencies from 470MHz
to 862Mhz, i.e. 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 PSU, if required, is also screened and it has short circuit protection
The two * F connectors required are included in the price, and they`re decent ones !
* four Fs if the PSU is purchased Also see four output version
Fully screened Mast Head Amp with variable gain (1 to 16dB on each leg) and a noise figure of 2.5dB. The maximum input level is 80dBuV and the unit amplifies frequencies from 470MHz to 862Mhz, i.e. will not pass FM/DAB. If required this should be diplexed
in after the amplifier. The amp can supply four TV points directly or more via a splitter(s) with power pass. As an example, if the amp were turned up to 16dB and then sent through an 4 Way splitter (with a through loss of 8dB) you would still have a “nett gain”
of 8dB 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 five * F connectors required are included, and they`re decent ones !
* seven if the PSU is purchased
Fully screened Mast Head Amp Kit with variable gain (12 to 25dB on each leg) and a noise figure of 2.5dB. Maximum input level is 60dBuV at full gain and 73dBuV at min gain. The unit amplifies 470MHz to 862Mhz, i.e. it will not pass FM/DAB. If required this should be diplexed in after the amplifier. The amp can supply four TV points directly or more via a splitter(s) with power pass. As an example, if the amp were turned up to 25dB and then sent through a 6 way splitter (with a through loss of 10dB) you would still have a “nett gain” of 15dB 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 PSU is also screened.
Note. I would normally advise the use of an amplifier of lower gain and capable of being turned down as far as possible, such as the one above, see article on this subject.
In other respects the two units operate in a similar manner, including PSU on any leg.
The seven F connectors required are included, and they`re decent ones !
All our PSUs are screened. Note, it`s only the RF section which needs screening.
Admit it, you think looking at what`s inside one of these is interesting, I know I do !
Internal (sometimes known as a “setback”) diplexer to combine or separate TV and FM and/or DAB. It should be noted that not all diplexers (or amps come to that) pass DAB on the FM input, all of our amps and diplexers do.
This unit does not have 12V power pass (for a M/H amp).
Loss approx 0.5dB, 1 Male to 2 Females.
See article on Diplexers.
Outdoor/Mast Head Diplexer to combine or separate TV and FM/DAB.
The unit is fully screened and its weatherproof enclosure means it
can be mounted outside.
Through loss is approx 0.5dB
See article on Diplexers.
The three F connectors are included, and they`re decent ones !
Outdoor/Mast Head Diplexer to combine or separate TV/FM/DAB and Satellite (930 to 2400Mhz).
The unit is fully screened and its weatherproof enclosure means it
can be mounted outside.
Through loss is approx 1.0dB
See article on Diplexers.
The three F connectors are included, and they`re decent ones !
Outdoor/Mast Head Triplexer to combine or separate TV and FM and DAB. The unit is fully screened and
its weatherproof enclosure means it
can be mounted outside.
This unit is not required if a Half Wave Dipole aerial is used (which we would normally recommend), under these circumstances the M/H diplexer should be used. It is used for three separate aerials, TV + FM + DAB.
See article on Diplexers.
The four F connectors required are included, and they`re decent ones !
1 UHF/TV input (or output) at 470 to 862MHz with a 0.4dB through loss
2 DAB input (or output) at 174 to 240MHz with a 0.3dB through loss
3 FM input (or output) 85 to 108MHz with 0.2dB through loss
4 Combined output (or input)
1 Input (or output) of lower frequencies
2 Output (or input) of combined signal
3 Input (or output) of higher frequencies
These four TV/UHF + TV/UHF diplexers are mounted in weatherproof outdoor enclosures
but can equally suitable for indoor use. Saddle and clamp for most secure connection of
the cable(s). The right hand picture show a close up of the PCB.
The through loss is under 1dB and through power is available on either (or both) legs.
Unfortunately there are no TV + TV diplexers available that are screened.
See article on Diplexers.

Variable “in line” attenuator
Male Co-
Variable from 1 to 22dB.
See article on attenuators
This product can also be suitable for those
who order an amplifier (rather than a splitter) when unsure of the signal strength in their area. By placing inline at the amp`s input it can reduce any excessive signal which may cause cross modulation. This may seem illogical but using an attenuator in conjunction with a “high gain” aerial will also increase your signal to noise ratio.
Fixed value “in line” attenuator
Male Co-
Available in 6dB and 12dB values
See article on attenuators
These attenuators can be useful in discovering if you have sufficient signal to use a splitter, rather than an amplifier. If your signal is still fine with one of these inline (see through loss
of splitters) a splitter will be fine, an amplifier is not required.
Fully screened Mast Head amplifier for both TV (UHF) and FM/DAB (VHF).
The unit has variable gain (15 to 27dB) on the UHF input 470Mhz to 860MHz. The VHF leg has a sloped fixed gain, from 2dB at 85Mhz to 8dB at 240Mhz.
The half wave FM dipole is the perfect aerial to feed FM & DAB into this amp.
The noise figure is 1.5dB and the maximum input level is 79dBuV.
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 27dB and then sent through an 8 Way splitter (with a through loss of 12dB) you would still have a “nett gain” of 15dB per output, less any cable loss.
The weatherproof enclosure makes it equally suitable for mounting on the aerial mast, on the wall, or in the loft.
The PSU, if required, is also screened and it has short circuit protection
The three F connectors required are included, and they`re decent ones !
