aerials - again :-(

Page 3 of 4  


Lol!
The cable that connects to the twig - where does the other end go?
Can you connect this directly to a TV (Unless it is already!)
Do you have a multimeter handy?

I'll bet that's it Sparks, it prob comes from the roof and connects to the water-but

As long as it is a water butt and not the butt of a Trans-Vestite.

...Quite...
I was asking to see if it went to a splitter, booster etc..!

At the moment it goes via the video, through a signal amp (to split the signal to a feed upstairs) and then to the TV.
I`ve fed it direct to the TV and the picture is the same as the "long" route above

Yeah... what should I expect from a length of co-ax i`d guess at being about 20m long (cheap-ass satellite installer lashed it across the roof of the house and down the wall) - it`s a standard terraced house with 1st floor to give you an idea of height / length
Are you just suggesting a simple resistance test between inner and sheath (to see if its shorted) ?
ISTR it has a 500V megger built in as well, but i`m not sure what the insulation should normally handle

Do yourself a favour and buy (yes, I know it hurts!) some nice new double screened coax and re-wire direct from twig to TV. If the pic is still crap then it's the twig. If the pic is OK then it was... the cable! Bear in mind that a decent 30m roll of cable will only cost around 12.
It's called elimination and it's really the only sensible start. You have a new twig in what you consider a good location and old coax. Maybe a little common sense won't go amiss and it's only what has been suggested throughout this thread.

Maybe that's the problem. Your "cheapo" attitude. If you want the best you have to pay and the best is never cheap.
Using used coax is never a great idea. Also the wiring sequence if you multiple TV's.
If you want to do a proper job but a high quality twig and some new double screened coax. Wire direct into your main freeview box or TV - no joints, no amp, no dis box. It has to go straight in. Then check the pic. If all OK then play around with the distribution cos then you have a known starting point.
If you have a digi box/freeview box wire from the RF out into a dis amp and then back down to all the TV's inc. the main one. More cables I know but the result will be worth it.
If you nice new hi-gain twig brings in all sorts of crap you may have to consider a small band pass filter but they're only around 10 and they filter out all the crap. Unlikely to be needed though.

Can U explain why you had to move the fixing clamp back in a little more detail.
BTW preserve with your DIY efforts the cheapo yello pages plonkers are usually just that:-(

Yeah, the previous aerial I lashed up there before xmas (only an 8 element) was mounted at the end behind the reflector, and the bracket it sat on only protrudes from the wall by about 8"
With the clamp in its "per instructions" position the reflector prevented me swinging the aerial in the right direction as it hit the wall :-} (at a guess it should point about 20-30 degrees away from the wall at the twig end)

If so the pressed plate reflector gives the impression it is only a poor "contract" grade aerial (as does the price).

Work out which transmitter you need:
http://www.dtg.org.uk/retailer/tx_details/_tx_index.htm
And see what group aerial you want. If you can use a "grouped" aerial rather than a wideband you will get better results.

You don't want it too close to the dipole (i.e. the active bit of the aerial that the coax connects to)

You would be better of with an aerial that can be back mounted by the sound of it. Try CPC for a Triax UNIX 52 for example.

I reckon the of the U bracket causing a problem is around 1000,000,000,000,000,000,000,000, to 1 !
On my 10ft mast I have an omni directional FM aerial just under my TV job and on the top of the mast I have a disc cone, only around 8 inches above the TV aerial. I also have various brackts holding them all in place.
None of this has any effect on the TV signal so your U bracket, unless you have it connected to a 240V supply (!!) is very unlikely to cause problems.
My money is on the cheap twig, poor cable or crap (or too many) connections/joints. Or of course the fact that it maybe in the wrong position/height won't help.
Sometimes you know we have to pay. Although I installed my own mast etc on my own house I have just had an aerial company install one on my brothers place. They came with all the gear, field strength meter the lot. It cost 130 for the twig (pro45) on a 10ft mast with T&K's etc. Not cheap but proper. And no grief with signal!
Don't buy cheap and instead of buying specialist equipment from the likes of Screwfix consider buying from a specialist. I chose the company who quoted the most!

Really?, On what do you base that statement?.

Well I'd very much hope that no one would connect it to the mains be rather silly don't you think. Good job you live in a strong signal area by the sound of it. Others are not so lucky!..

Quite.
Well good for them then. Trouble is a lot of so called aerial riggers are no more clued up that the average DIY'er ,mores the pity!.

Well you can obtain good makes such as Antiference and Triax form www.cpc.co.uk and from some good wholesale outlets the DIY shed ones aren't that much cop from what I've seen of then:-(
Pity the original poster can't post a few pictures somewhere as they say a picture is worth a thousand words. In case you haven't seen it here's what"not" to do, courtesy of Mr aerial himself, Bill Wright!.

My own knowledge, experience and the knowledge and experience of colleagues.

Yes, it would be really silly. Rather like your sacrasm here really.

Yes, quite.

Agreed BUT surely you stand more of a chance when you can "talk" to a proper supplier and purchase the recommended product. Try phoning screwfix and asking for advice on signal propogation!

A dead link so that's no use at all!

Well FWIW the day job involves designing aerial systems for receiving and transmission, and I can tell you that small amounts of metal in the wrong places can and do upset things quite badly sometimes, and at less than the chances you've quoted!.

Not at all most of what you have there is too closely spaced and I presume that the ommni is perhaps one of those halo things or do you have a turnstile arrangement?.

Regretfully because Joe Public will spend a fortune on his telly etc they will be dammed if they will spend any money on a good aerial system or if they do then its the "best price" that will always win and that usually means the ones straight out of rouge traders!.
So Joe has bought it upon himself to some extent!.

Works fine for me?..
