TV cables, a difference?

Joel

You can certainly use the cable for normal TV. In fact most installations use that cable now which is suitable for Digital TV. Rather than change the wall plate just go to a TV antena installer and get him to make up a tail with a F connector on one end and a normal one on the other end to plug into the socket on the TV. An F connector is one that screws onto the wall plate.

Just keep in mind that you are not really saving much by doing this. Cable is really cheap. I see alot of people that will spend big money on an aerial then connect it to the cruddy cabling that has been in the house for decades. Running cables is normally not as hard as it seems. If the cables are not 100% then the no matter how good the aerial is the reception will never be good. This goes for connectors as well.

That being said if the cables are in good condition I would not change the connectors or wall plate. Just make the fly lead fit the wallplate. It is probably an F type connector, so just make or buy a "Belling Lee to F" fly lead and you away.

P.S. some places call belling lee connectors "PAL", either way they are the push on type for the TV etc, they come in male and female.

Hope that helps.

If the cable is ratty you can use it as a mouse to feed new cable, installing an antenna is not always as simple as it seems and you should find an optimum position on the roof, one metre sideways can make one hell of a difference in some situations.
Height of antenna can also be crucial and moving up and down a metre of so can give you up to 20db gain difference.
Go for the best antenna you can afford, there is a difference, keep away from the el cheapo's as you will find that the plastic components will fall apart in a matter of months as they are not UV resistant.
Bigger is not always better, I use a log periodic antenna that is just over one metre long and offers 12db gain on VHF and UHF, that is more than those enormous 8 foot combination antennas and less obtrusive, the down side is it starts on channel 6 so we cannot receive ABC analogue, but as ABC digital (Melb) is channel 6, not a problem.
I'm not sure what your channels are but you may get away with a UHF only antenna, tell me what you have and I can tell you what antenna to go for (log periodic B4-B5 or B4/5 or even B3-4-5)
F to Pal fly leads are available off the shelf but generally are pretty crappy, get a tech to make you one, will cost about the same but will be far superior quality.
With existing cabling you can also insert an F connect splitter in the system, go for a good quality splitter if you need to put one in and don't be tempted with the cheap and nasty screw and saddle types, far too much loss and digital TV does not like it, for memory I think they lose about 5db per point, F types typically lose about 1 db or less.
F connect are easy to fit yourself, just buy the screw on type, once on they won't fall off, the only reason most techs don't use them is because they are hard on your fingers when you put them together, but if you are only doing one or two, who cares, when you are doing a few hundred, crimps are quicker and easier, but not neccessarely any better.
If you need tyo buy coax make sure you get RG6, do not be tempted to buy RG59 as it is not as good and there is too much loss, if you can get at least dual shield, foil and braid, better still get tri or quad shield.

Radio parts in West Melbourne and Malvern sell off the shelf F-type to PAL flyleads that are high quality RG6 for a reasonable price. I use one into my HDTV card in my PC and get 98.9% signal all the time.

As has previously been mentioned, dont skimp on cable, put in decent quad shield RG6 and f-type connecters all the way through until they come out the wall plate. The only PAL connectors in the system should be into the TV/Video. An F-type crimper is about $25 and a coax stripper is about $35, worth it if you have a bit to do.

But bear in mind that it was a dish not an antenna, completely different story, all you need is a clear line of sight for a dish (yep, theres the satellite we'll point at it, theres only about 5000 to chose from) terrestial is a completely different story and is subject to reflection and all sorts of other nasties that you can't see without a spectrum analyser, but.............................you may just get lucky.
Another point where some people have come unstuck, I'll get rid of my satellite TV and use the coax, works a treat but I lost my broadband connection, be wary.

Right, I was thinking of someone I know who wishes to remain nameless who used existing cable for an antenna job on an Optus fibre optic setup.
Cheap antenna's???
Steer clear of Bunny brands, stick with awell known like Hills, and er, um it's a green thing and I've forgotten the name.Matchmaster thankyou Mr memory
Don't go to Dick Smith or Tandy, too expensive, a local TV repair place will have one, and advice too which is a big plus.
You should get something decent for under $100.00

TRy a log periodic and a decent clamp, then use s digital set top box, end of all problems.
Small antenna, high gain, not prone to movement in wind and a big plus, 75ohm impedance, no balun to break down.

Multiple antenna and diplexing is also an option.

JDub,

The house I just bought had no aerial and we were relying on rabbit ears. Then somebody told me that if you have any reception at all digital TV will give you a perfect picture. I was a bit dubious about this but bought a SD set top box and have had a perfect picture since, only using rabbit ears which are concealed behind the corner TV unit at floor level.
When I say perfect picture I mean it is like watching a DVD.
A cheap option with no stuffing around.

Set top boxes start at around $130 but you get what you pay for.
Avoid brands such as Teac, Akai and stick with better known names like Thompson, Emtech etc who are big in Satelite decoders, which is the same technology, they work exactley the same way, just from a different source.
The better boxes will work as low as 30dbuv while the cheaper ones will start to drop out at about 50dbuv.
Expect to pay about $200-250 for a decent SD (standard definition) and unless you have a 100hz or plasma TV I wouldn't even consider a High Definition.
Apart from picture quality that is like watching a DVD you also get multiple SBS channels, programme guides, music channels and an information bar.
Some have teletext too, if you can be bothered waiting for it to load.
Channel ten Melb occassionally run multi channelling on some sports events so you get to chose which view you want, doesn't happen often and I watched 4 different aspects of the Malaysian Grand Prix last year.
They never tell you when it's happening though.
And, ABC have another channel too, its on 21 digital and is an alternative to whatever is on the normal analogue stream.
The better boxes also have fibreoptic audio out so you can hook into a home theatre.
I've had one now for 3 years and would never go back to analogue.
