Which companies have run the Channel 3 services in the Emley Moor transmitter area
When I was working in TV Servicing during the analogue days we had male and female plugs with 75 Ohm loads built in, but I haven't seen them advertised for some years. Correct termination is crucial when dealing with RF. An aerial is designed to present a 75 Ohm impedance at the connections and the input to any TV tuner is designed to 'see' that 75 Ohms so that the full amount of signal passes into the first stage of the tuner, usually a tuned RF amplifier. If the tuner does not 'see' 75 Ohms, there is a significant loss of signal being transfered into the tuner. Added to that is that mismatching can give rise to internal signal reflections in the cabling, which can mean total loss of signal at the tuner input! And that loss could be frequency specific so you might get good signals at, say, 500 MHz but little or nothing at 510 MHz! Plus you can get some very strange effects due to standing waves in the cables! (Isn't RF fun to play with?!)
Passive splitters are always designed to maintain the impedance matching but only when all outputs and inputs are connected to 75 Ohm devices. Unplug any one and the matching is lost, often resulting in the mismatch effects I described above. Using Ohm's Law you can calculate the values of resistors needed for each leg of the splitter, remembering that all of them must be the same value else the signal is not shared equally.
You can make a terminating plug easily though, all you need is a plug of whatever gender you require and a 75 Ohm wire-ended resistor. One lead is connected to the inner and the other to the outer - simple but can be a bit fiddly. Depending on the actual construction of your chosen plug you may want to solder the wires to the centre pin and the star-shaped fitting that usually connects the outer sheathing of the coax cable to the outer body of the plug. The centre pin wire can usually be passed right down the bore of the pin so there is no risk of it shorting to the outer and it can be trimmed so it does not protrude beyond the pin.
When you assemble the terminating plug don't worry that the end of the resistor and its wire are a little visible, they are at 'ground' potential.
If though you don't want to fiddle with a plug and resitor, you could always get a 75 Ohm F terminator and an F-Coax adapter, such as the ones shown at IEC Spiral Connector 75 Ohm Terminator, (other sources are available).
Note that all references to 75 Ohms in this context is to the presented impedance of the device(s) at the rated RF and not to any DC resistance (an aerial often measures as a short circuit to DC!).
Does that help?

MikeP: Yes, thanks, it does help.
I ask because I have an aerial which feeds one room and which I'll be fitting a splitter to in order to feed another room. If there is one room which doesn't have a TV in when the other does I can fit one of these terminators if the picture is affected.

Glad to be of assistance. Using passive splitters can give some unexpected problems so I would suggest that if you still want to use a passive, rather than an active that gives gain but isolation between outputs, then it might well be worth having the terminators available and connected to unused outputs to prevent odd events. Note that you always get some loss of signal strength with passive splitting, even when all outputs are properly terminated into 75 Ohms.
Such is the fun of electronics technologies, especially when working with the higher frequencies. When you start looking at the signals in the 10 -100 GHz bands it gets even more critical to have properly designed distribution. I well remember a taxi firm in Nottingham using an improperly set up VHF transmitter that spread interference across not just the VHF radio signals but badly affected local reception of UHF from the Kimberley transmitter and also some immediate neighbours' satellite reception! And all because the transmitter was not 'matched' to the dipole aerial they used.
Let us know how you get on with the signal distrbution.
