Contact Us		Splitters and attenuators Contents Satellite LNB signal attenuator UHF signal attenuator Variable attenuators UHF splitters SkyLink splitter 2-way passive splitter LNB cable splitters Combiner HDMI splitters, connectors and leads DIP2 SAT/TV combiner or decombiner/diplexer see page 15 V24-310 FM/DAB/TV combiner or decombiner/triplexer see page 15 Satellite LNB signal attenuator choice of 3dB to 10dB £1.99 LNB signal attenuator for use with BIG dishes. Designed to attenuate the signal but passes the DC supply to the LNB. May vary slightly from photograph. (Some Grundig Sky Digiboxes reportedly do not work well if the LNB cable is less than 5 metres. An attenuator can compensate for this. But note that Grundigs mainly suffer from power supply faults so check this first). Amstrad DRX895 is also reported to suffer from problems if the signal is too strong. Order two attenuators (one for each LNB input). Try 6dB (or 10dB if LNB cables are very short). ATS3 3dB attenuator FM/SAT DC pass ATS6 6dB attenuator FM/SAT DC pass ATS10 10dB attenuator FM/SAT DC pass £1.99 Qty UHF Attenuators When a Freeview receiver detects a signal which is too strong, its automatic gain control (AGC) adjusts the tuner gain down to compensate. If the signal is _way_ too strong, the AGC tries to protect the receiver by overcompensating and turning the gain down much further. The result is often that the signal level display is quite low when the signal is way too high. Adding an attenuator reduces the incoming signal, causing the AGC to "relax" and the signal reading will go up! So you can't rely on an on-screen signal indication to measure signal level. It's purely a guide (and not a very good one). The only way to measure an aerial signal is with a properly calibrated aerial signal meter. Unfortunately, the cheapest one we stock is well over a hundred pounds. I did some tests on my own aerial system (which gives perfect results on all channels). I have a good, strong signal but not overly strong. I found that I could insert 30dB of attenuation in the aerial input before the on-screen 100% indication started to fall. In the case of a way-too-strong signal I would expect to need more than 30dB attenuation to get the signal down to a reasonable level that the receiver could handle. Perhaps even as much as 40dB. If you have a really strong signal, you might need a couple of fixed attenuators plus a 20dB variable attenuator to get the level right. There is very little to go wrong with our attenuators, apart from the adjustor breaking off. There's no electronics inside. Please note that attenuators can be "daisychained". For example a 3dB + a 6dB will make a 9dB attenuator. UHF attennuator UHF attenuators for use with aerial. (Not suitable for dish signal). Choose attenuation required from drop-down list, below. (Never connect an attenuator directly to a TV aerial socket. It will put excessive strain on the connector and could cause expensive damage. Use a short, flexible lead.) ATU3 UHF 3dB attenuator £3.50 ATU6 UHF 6dB attenuator £3.50 ATU10 UHF 10dB attenuator £3.50 ATU12 UHF 12dB attenuator £3.50 ATU18 UHF 18dB attenuator £3.50 ATU24 UHF 24dB attenuator £3.50 Qty   Variable UHF attenuator 20dB adjustable attenuator with KNOB Not sure how much to attenuate your amplified UHF signal? This is your answer. (Not suitable for dish LNB signal - see below). Use this adjustable UHF attenuator for Freeview if your signal may be too strong. The UHF variable attenuator is also useful for minimising interference caused by too strong an aerial signal into a Sky Digibox. Connect as close to the aerial input of the equipment as possible. (Don't attach it directly - use a short cable). Note: made by various manufacturers so connectors may be male or female IEC TV socket, or both. CONNECT86 UHF attenuator 20dB variable £5.95 Qty Variable attenuator with DC pass (up to 500mA) for use with LNB or UHF aerial. Frequency range 5MHz to 2400 MHz. Adjustable from -3dB to -18dB. Uses threaded "F" connectors. Screwdriver adjustment. Click image for larger picture. Requires short lead. AV-315 attenuator -3 to -18dB variable £9.95 Qty MA1620 Adjustable 0-20dB attenuator, coaxial connector version  Use a short, flexible lead. Frequency range: 5 - 1000MHz Dimensions: 50 x 30 x 20mm Weight: 41g S122-730 UHF attenuator 20dB variable £4.95 Qty UHF "Y" splitters A 2-way passive splitter loses around 4dB of signal. If you have plenty of signal, this shouldn't matter. The passive splitter should be connected as far from the aerial as practicable in order to minimise the risk of interference affecting the weaker signal in the final run of cable. (In a weak signal area you should use an amplifier. Always put amplifiers as CLOSE to the aerial as possible - the loft is ideal.) Note: all 2-way splitters pass approximately 40% of the signal to each output. Cheap, unscreened, UHF "Y" splitter Unscreened cheap version 010-0115 (connect one aerial to two TVs) Not recommended for weak signals where interference could be a problem. 010-0115 UHF Y splitter £0.50   Qty Deluxe UHF "Y" splitter Fully screened AP00090 (connect one aerial to two TVs) Lower loss version. Male IEC input socket and two female output sockets for standard TV plugs. AP00090 Deluxe UHF Y splitter £3.95   Qty SkyLink compatible passive splitter which is capable of passing the 9 volt supply from the Digibox "RF Outlet 2" and allowing the Remote Control signal to go back to the Sky Digibox. As with all passive splitters, this unit will reduce the signal by around 4db (60%), thereby limiting the length of cable that can be used. However, it provides a very cheap solution where amplification is not required. F = Female, M = Male IEC socket. (Male IEC TV plugs must be used for all connections. Solder the centre pin. A COLCM TV coupler and a CO01 male-female UHF lead is required for the connection to your Digibox.) Where amplification is required, please use a SkyLink compatible Amplified Splitter instead of this passive splitter. Please read our NOTES. Note: all 2-way splitters pass approximately 40% of the signal to each output. SkyLink 2-way splitter indoor IEC-conn 1000MHz £1.95   Qty Tick to Include COLCM TV coupler (female-female) £0.39 Tick to Include CO01 - low cost single-shielded RF lead £0.53 Power-Passing Splitters The following splitters may also be used outdoors, provided that the 'F' connections are adequately waterproofed with self-amalgamating tape. 2-way passive splitter with threaded "F" connectors is suitable for splitting a TV aerial signal. It is also suitable for use where a masthead amplifier is fitted because it allows the amplifier power to pass from either output back to the input. It may also be used as an LNB feed splitter to two satellite TV receivers where it may permit ONE receiver to work at a time while the other is in standby. However please note that the resultant signal loss (4dB) is likely to be too high for reliable operation. Note: all 2-way splitters pass approximately 40% of the signal to each output. A73203 2-way splitter F-conn 5-2300MHz 2 DC pass £3.25 Qty If you want to split the dish cable, click HERE 2-way passive splitter with threaded "F" connectors is suitable for splitting a TV aerial signal. It is also suitable for use where a masthead amplifier is fitted because it allows the amplifier power to pass from ONE output only back to the input. It may also be used as an LNB feed splitter to two satellite TV receivers where it may permit ONE receiver to act as "master" to control the LNB polarisation. Note: all 2-way splitters pass approximately 40% of the signal to each output. A22373 2-way splitter F-conn 5-2300MHz 1 DC pass £3.25 Qty UHF Splitter/combiner 4-way with "F" connectors type PAS1243/001 (as in "Piping TV" book). (Does not provide bypass for SkyLink signals). 5 MHz to 2300 MHz 4 way splitter. Order 73237 splitter/combiner. MORE INFO. Note: If used as a splitter, will pass a very much reduced signal to each output. 73237 4-way F splitter-combiner £5.95 Qty Send this page address - CLICK HERE - to a friend !
