Just been quoted £254 + VAT for a "DMX5" 32 element "high gain" X type
aerial from Skyforce!! I nearly wet myself.... Apparently, where I live (WA6 6 - Frodsham) I'd need a wideband aerial - I told him that the transmitter says I need a grouped one (C/D), but apparently "wideband aerials are recommended for digital" and "I wouldn't be able to get channels 40 and 43 which I'd need for radio. I pointed out that I already got all of the muxes, range 56 - 68, so he muttered something about group C/D was opened up a few years ago to add channel 48 too. At that point he'd lost the job anyway. Signal meter was used to test my existing. He got 40db on channel 66 apparently. "Tested" what he could get by standing in the garden with an aerial (with half an element missing) over his head, with his signal meter round his neck (using co-ax as his neck strap!), and got 45db apparently on that one. He estimated "add 15db" for putting it up on the roof, but I'd need about 70db for digital. I want to split the signal, so he said add another 8-10db for splitting. Whole quote was £168+VAT for the aerial (fitted), £38+VAT for each extra output and £10 for a 4 way splitter on the mast. Now I am making a lot of assumptions here, 'cause I don't know much about aerials etc, but I get the distinct impression that this is all way over-charged ********. Comments? Bill - care to libel Skyforce? Matt |

Leaving aside the technical side, you do seem to be haveing quite a bit of work and a large aerial so maybe not that expensive. My car was at the garage for less than an hour for its annual service and cost £125. Caravan annual service cost about the same. -- Regards, David Please reply to News Group. |

Can you not do the job yourself ?
I avoided the problem of getting on the roof by using wall brackets which I screwed onto the gable using strong rawl bolts, this now means the aerial can be accessed without ever going on the roof again, and it is a far stronger job than a chimney lashing. Then it's a simple matter of a length of mast with the aerial attached, alignment is again so simple just ring your wife in the lounge using a mobile phone, and twiddle the thing around whilst she watches the signel strength...

Maybe a decent four way distribution amplifier would be the way to go. Regards, David Please reply to News Group. |

But the aerial is only a small 30 cm job, and the "extra outputs" ath
£38 + VAT each consisted of running some cable outside the house and shoving a hole through the wall - no chasing, no end plates (not that they are a good idea anyway), just lashing cable round the exterior of the house. £38+VAT each!?!? The aerial at £168+ VAT fitted is an affordable price (ish). But I don't think what I'm wanting is that much work! Matt |

That's what my research was telling me - to be honest, I'm getting
quotes to make sure that it is worth not doing myself instead. But at the prices I'm being quoted, I think a job done myself might be the best route. Another guy just came round to quote me £372, without even looking at the existing signal. Next stop is a local (non-0800) installer..... Matt |

Apparently, where I live (WA6 6 - Frodsham) I'd need a wideband aerial
- I told him that the transmitter says I need a grouped one (C/D), but apparently "wideband aerials are recommended for digital" A lot of them only carry wideband. It makes their lives more simple. Signal meter was used to test my existing. He got 40db on channel 66 apparently. "Tested" what he could get by standing in the garden with an aerial (with half an element missing) over his head, with his signal meter round his neck (using co-ax as his neck strap!), and got 45db apparently on that one. He estimated "add 15db" for putting it up on the roof, That's absurd. There's no fixed (or even approximate) relationship between reception in the garden and on the roof. but I'd need about 70db for digital. I want to split the signal, so he said add another 8-10db for splitting. That's absurd as well. No way would you install a big aerial and then **** away the signal by using a splitter. Use an amp. Whole quote was £168+VAT for the aerial (fitted), We charge £150 + VAT for a TC18 on a 12ft mast with two chiney kits, cable, etc. Without a full spec the quote is meaningless. £38+VAT for each extra output That's about right, but you do want outlet plates. Forget all this nonsense about running the cable direct to the receiver. If you're that short of signal you should have an amplifier. The thro' loss on two 'f's and a barrel can't be measured. The VSWR is virtually perfect. Now I am making a lot of assumptions here, 'cause I don't know much about aerials etc, but I get the distinct impression that this is all way over-charged ********. Well it's certainly ********. The firms in the Yellow Pages with the big ads listing lots of diverse areas covered are franchises. In some cases you're paying a £50 introduction fee. Bill |

Hello, We're not talking about cars or caravns, it's about TV aerials. The quote is not too bad for the aerial which includes fitting, cable and VAT. For Winter Hill you do need a Group C/D horizontally polarised aerial. You shouldn't have too much difficulty from where you are - I know the area well. Just take a look outside, how many aerials do you see that are massive or have preamps? Then make your own decision! You would be better ordering a Group C/D and seeing if you can put it up yourself. Then get a distribution amp, not one of the cheap B&Q ones. Save a fortune. The main problem is that this new digital stuff has given some people an excuse to charge what they can get away with. Most fitters will not even guarantee their own work by guaranteeing their installation can provide a good enough signal so the picture will not break up. Some will say they only fitted the aerial and are not responsible. Some will fit small aerials slightly off and try to sell a preamp, or fit an aerial ad a preamp. There are a lot of cowboys, so watch out. One I got a quote from was a member of a recognised institute but tried ripping me off. He went outside to look at what others were using and which way they pointed. Mad! If you're interested in Skyforce, have a look on the Companies house website to check they are a VAT registered company, then look at the turnover etc, or see how long they have been established and whether they have traded under different names or had directors associated with companies no longer around. |
