Thread: TV cableing

if, by extra cabling you mean stuff going to the bedroom, no. It is all handled through the transceiver.... the bottleneck in these systems is the number of "ins and outs" in your devices. For example to fully set this up in the optimal way, an A/V Amplifier (ie: Denon Home Theatre Amp AVC-A1) is required ..... this enables numerous sources via coaxial, optical and signal wire...... the other bottleneck is that to be able to control each device you need two things - a universal remote that can learn and has enough categories for all the components (or you need two remotes for everything....or spend your time running back outside in the cold to get the remote you forgot
....and the number of infra red repeaters you have with the unit .... these are small "cubes" that go from the transceiver to the fronts of the devices and repeat the signal from your remote/s....... man this is mind-numbing to put down in text .... if you dont have enough of these, you can't control all the bits.

Our unit was bought from JB .... it works fine but is upset by two things - our microwave, which is a total pain in the .... because This Old House is on when my wife is usually defrosting something before making dinner! (she is in the lounge watching TV and I am in the bedroom swearing at the TV because of the interference) - and wireless networking, which is bloody bizarre seeing the transeiver is basically one as well! I feel certain those bugs would be ironed out by now.

As ours is two+ yrs old now there would be better ones around, but I havent had time to look.

Sorry for the overly long reply - the unit we have is generic so I can't see any brand - a high-end hifi place ought to be able to help...... also there is a brilliant magazine called electronic house (USA) (there must be others out now) that go into great detail abt this stuff

hope all this is at least a little helpful

Set up some mirrors in different rooms so you can sit in the bedroom and change the TV in the loungeroom without having to get up and manually change it.

I personally think boosters are over rated.

I feel confident that such labour saving devices still have a place in our lives .... especially where it alleviates the need for crawling around in ceilings and under floors to get a TV piccie in other rooms.......after all, you never know if there's some sinister soul observing our every move from the other side of said mirrors (with deference to Mr. Blair/Orwell)

You obviously don't live far enough away from a transmitter to need one or your only running one TV anyway.

You've been watching too much Poltergeist III

Sorry man but I never watch those sort of shows.

I only made this post to become a gold member.

Try putting a bit of aluminium foil behind, under and over the microwave. This may well reflect all the spurious signals back in another direction and give sufficient shielding.

Pity I didn't see this one a while ago.
Most of the posts are correct and running 30 metres of coax you are going to lose up to 4 to 7db depending upon the frequency range of your local transmitter.
Remember that db runs a logarithmic scale and not linear, 3db is a doubling or halving of signal so 9db is a 800% gain!
Amps are good but this depends upon the type of amp, the cheapy dick tandys are generally just crap but you can get fair dinkum distribution amps at reasonable prices.
I work as a technical rep for Laceys TV www.laceys.tv and they have an office in Chipping Norton which may not be far from you, wander in and ask a few questions and I feel sure they can supply the gear and give you the correct advice as I don't know what sort of signal levels you are running.
For a few connections around the house I think that screw on F connectors are every bit as good as crimps, just that the pro's are doing hundreds and they are slow to apply, but for a one of, who cares.
The difference in price between dual and quad shield is minimal, unless you go to BUnnies, and I would go for quad every time. Having said that there is also tri shield which is also good.
Do not ever use RG59, too much loss and as someone else pointed out anyone who uses airspace coax should be shot with a ball of their owb $h1t.
Kingray amps are good but I think that Alcad are as good and cheaper, try to get an amp that is rated close to the maximum output that you need.
Operation amps run best flat out and can be noisy when turned down.
Also consider Fracarro.
Have a good look at your antenna too and consider getting a high gain unit to improve signal strength.
Apart from splitters you can also use drop taps and specify the signal loss at each run.
Optimum signal strength is 70-75db and if you use an amp and boost this to 100db you can then use a 4 way drop tap with a 20db loss + 3-4 db line loss and have the correct level at the tv end.

Have a look at www.laceys.tv as there are some system designs on board that could be of use to you, and they are not expensive.

Thanks Iain,

Laceys' local office is not far (15km), I will check with them.

Regards,

Theva

I am not surprised by that perception as most of the "boosters" sold in retail stores have poor noise figures and do little to improve the situation.

Ad to My previous comments.
Stay away from cheap boosters.

I have done some realy edgy installations with high gain low noise boosters for long range work and a good, properly selected & adjusted amplifier can produce stunning results.
Like lismore stations from Mt Gravatt (Brisbane) on a good day.
Brisbane stations from the Gold Coast & down 17 stories, in addition to the local re broadcast.

But you need a skilled operator and good quality hardware.

Barry, to explain, I was introduced to this site by a mate and was on leave at the time. As I was only new I decided to have a look and as this is a Forums page decided to have my say. Unless that is if the rules have changed? (ha ha)

Any way, went back to work and if you notice they have dropped off considerably.... Dag Nabbit

Cheers

What the hell is a Dag Nabbit, sounds like it could be a prohibited species from the good ole US of A.

(if you make the connections with this one I will take my hat off to ya)

........ you got any pictures of walter brennan's ankle?

wonder if you will get it ?
