After some very helpful input some months ago, I am still struggling to receive a decent (useable) signal on CH48 from the Nottingham transmitter. I had previously answered a number of questions on the strength/quality of the signal on all the Nottingham channels but had run into some issues relating to the status of the feed cable.

I apologise for the delay in getting back to you but this problem is now resolved and the integrity of that feed has been confirmed. I am receiving a reasonable level of signal on CH48 (averaging 8/9) but the signal quality is only 1/2. All other channels are providing perfectly useable signals. Do you have any suggestions as to what I should consider next please?

Loft mounted aerial at 75m elevation, 5km from the transmitter.

Hi Ted. Just been having a recap on those previous posts. if you recall you did some quality and strength measurements with the aerial direct to the TV for each multiplexes UHF channel.
Results in this post https://ukfree.tv/extras/inreplyto/1032782 all other equipment out of circuit and switched off. The results showed this decrease in quality and strength with increasing UHF channel !

I did mention at the time about doing the same but with just the filter in circuit. Could you do that and post the figures please.
Depending on results, that will hopefully give me a clue about the next possible check.

Chris.SE: Apologies for the delays in getting bach to you - the number of stairs between the aerial and the television always seem a bit daunting!

I have re-run the strength/quality figures as requested with the filter and the amplifier in and out of the system. As far as the simplistic tv measurement capabilities are reporting, the filter makes no difference to the values either with the amp or not.

The amplifier is, however, essential:

Raw aerial figures with amp
CH Str Qual Str Qual
21 2 0 10 10
24 4 4 10 10
27 3 4 10 10
33 2 0 9 10
36 3 1 9 8
48 2 0 5 3

I hope this may shed some light on the possible problems. Thanks again

Ted

Hello Ted. Hmm. I come back to a remark I made to an earlier post about the strength dropping with increasing channel number (and therefore increasing frequency) and that pattern exists without the distribution amp/splitter and you've confirmed that the filter is making no difference to the figures.
This would seem to suggest that it's not interference, but some issue with the aerial end. As the aerial is in the loft, then water ingress isn't a likely cause either.

The thing I notice with this last set of results is that the strength is now lower than a comparable set of figures a while ago, and we've just had a period of extremely hot weather where metal joints are most likely going to be affected. As much as it might have seemed unlikely, I'm thinking it's some fault with the aerial, either the connector box to the dipole itself, or if there's a balun, to the balun or balun to dipole or the balun itself.

You say this is a 10 element aerial, roughly how old? Is it a "conract" type with a small metal grid on the back or does it have a few rods as a reflector?
If you know what it is, or it's gain that'd be helpful. But I'm coming to the conclusion, especially if stairs are an issue, that it would be simpler to just replace the aerial.

You don't need anything elaborate considering your proximity to the transmitter etc. so expensive large multi-element aerials are not needed, but maybe something with just slightly better gain than what you have at present. There are quite a few reasonable "K" group aerial about, but as you have a filter a "T"/Wideband would probably do.

What more can you tell us about the existing aerial? (And the amount of space in the loft where it is?).

Chris.SE:

Thanks.

It is clearly a fall-off of signal with increasing frequency but I hadn't considered the aerial as suspect - largely because, as you say, it is well protected and undisturbed. I will however go in and inspect it and the connections.

I estimate it is around 15 years old - probably a Philex or similar as it was bought from Maplins. It has rod reflectors. I will let you know if there is any additional information on it when I get to it.

It is pointing out through a roof that is boarded and slate covered with no felt or insulation (1910 house). There is around a clear metre front and back.

Well, no point in procrastinating. I've just been to look at the aerial and I can see nothing physically wrong with it on a visual inspection. I have photos of the aerial and of the connection box but can't see a way of sharing them with you here. The cable termination looks solid and clean as expected.

There are no obvious maker's marks on it so I can't help any further on that score. In case I have misled you, there are 10 'X' shaped directors, a short solid stub and a two loop dipole. There are 4 reflector rods each side.

If there are any other basic checks I can make on it, please let me know. It certainly doesn't look as though it needs replacing!

Unfortunately there is no way of sharing pictures here. In the past people have uploaded to a site where a link can be provided, or found a picture of something identical and given the link to that. I've found this one which sounds almost identical, Part Number 27884D4 -
https://www.philex.com/products/product/slx-4g-48-element-digital-tv-aerial/

If you click on the image it shows an enlarged picture.
This user guide for the "kit" version, I don't know how similar yours was -
https://pdg.cef.co.uk/downloads/pdg/philex_27884k4_a_datasheet/philex_27884k4_a_datasheet.pdf

Are you able to see how the connections are actually connected to the dipole, nuts and bolts or rivets etc.?
What is the loop resistance to the aerial measured from the connection that would go to the splitter?

Chris.SE:

Yes, that is the same basic aerial - the version I have, because of its age, doesn't have the inbuilt 4G filter. The one I'm using was supplied by the project (Televes 404401).

I have checked all the connections. The cable terminates on a balun pcb which is capacitively coupled (through the pcb varnish layer) to the dipole. The cable from the aerial to the splitter is only two metres long so, although I have checked end to end continuity, the loop resistance is well below my measuring capacity.

Whilst up there I also checked the aerial alignment both vertically and horizontally to verify that it is pointing to the Nottingham relay, based on the published latitude and longitude.

You can see why I'm getting exasperated.

And just to be absolutely clear, because of the capacitive coupling, there is no DC loop circuit from the cable end through the dipole. The pcb is screwed down to the ends of the dipole loops with self-threading screws.

Ted Slater:

Frustration is probably an understatement.
As the aerial has a balun, I'm glad there's no loop resistance, at least no short circuits!
With only a 2m length of cable, I would guess it's pretty obvious to check that it's not been crushed at any time which could affect its performance.

Now, in such circumstances, one has to question the (not so?) obvious. As you've checked the cable from the splitter to the TV and done those other measurements, one is left with suspicions about the aerial (especially as we both I guess, are out of other ideas).

Lofts are subject to extremes of temperature and at times there could also be condensation. Different metals in contact with one another can also have reactions over long periods of time.
So although the connections may "look" ok, I'd be inclined to unscrew everything that can be - including the dipole to balun. Make sure everything is spotlessly clean, very carefully use meths to clean contact areas only, maybe use a cotton bud, don't want to upset any varnish!
When re-assembling pay special attention to the braid clamping screws making contact with the PCB and the braid with the PCB if there is copper under it.

I really can't think of anything else at present, this has to be a really odd one.
