The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Hannington (Hampshire, England) mast?

Thanks Chris, I have installed the SLX Megaboost 4 way aerial and tested all structured outlets in the house individually direct from the aerial ie. not though the boosted 4 way amp/splitter, and they all get 100% signal quality and strength (which I guess is too much) on the test TV. Unfortunately as you predicted when I connect them through the 4 way amp/splitter they all still show 100% strength, but quality of only 40%, so I guess too much signal!? I've tried a 10b attenuator between the aerial and the amp/splitter, but doesn't improve things much. The log periodic aerial spec only shows a 6b gain from the aerial, but 16b for each output on the amp/splitter.

Is it best to try the variable attenuator between the aerial and the amp/splitter, or shall I ignore the amp and just try a 6 way splitter if the signal is really strong!?

What do you think?

Colin Whatley:

You should have bought that particular variable attenuator that I mentioned at the time, it's now out of stock (I'll see if i can track down a similar one later). Yes, if the quality is dropping to 40% with the amp it could well be too much signal.
But what sort of figures were you getting for this 10dB attenuator between the aerial and amp?

If the aerial direct to a TV outlet was 100% signal and quality, it might be bordering on too much but if there's no breakup of picture or sound over a period, I wouldn't regard it as necessarily any problem. What I would try first is put the 10dB attenuator between the aerial and a single outlet (no amp) and see what figures you get. This will give you and idea of how much signal you've actually got.
Then try the 10dB attenuator between the amp and an outlet (but not the one with the PSU) and see what figures you get - again this will start to give you an idea of what is going on.

Attenuators are a very much under-rated diagnostic tool!

@Colin Whatley:

As I understand it you get strong 100% quality signals from the four outputs from the mast head amp/splitter.

You want to split two of those two ways each?

If so try two cheap passive splitters similar to:
TV Aerial Metal Coaxial Signal Splitter 2 Way 1 Male to 2 Female Coax | eBay
if fitting in an accessible place,
or perhaps ones with F connectors might be better if they have to be in the loft near the aerial similar to one of these:

Brian Gregory:

You understand it wrong. The signal he's getting from the amplifier outputs appears to be far too strong. Until he discovers how much signal he's getting from the aerial as well as from an attenuated amplifier output, it's not possible to decide the best way to go. If for example he's getting enough signal direct from the aerial, I would be suggesting trying one of the 6-way splitters in the 2nd link you posted, which I'd already looked at yesterday.
You need to analyse the situation before rushing off to make suggestions.
(As an aside, have you bothered to read he reply to your own post?).

It just been announced (personally I'm disgusted and will be complaining to OFCOM and Arqiva) that COM8 is to close on June 22nd see 22 Jun 2020 - Important channel broadcast changes | Freeview
so we'll be loosing Channels 4+1 HD, 4seven HD, TJD HD and a number of +1 SD channels. Other COM8 channels will be moving multiplex (some to COM7? & room possibly on PSB3) as well as COMs 5 & 6.
Not sure how your COM7 signal compares to COM8 and whether that will have any effect on the way you deal with this.

It will depend on what frequency of email you signed up for, even then it's not my fault if the site hasn't sent an email when it should have (I'm getting my weekly ones, some people sign for daily etc.) have you changed your email address? If you didn't keep a note of where you posted there are still two ways of finding them -

There's a link to all your own posts at the end of each post (as well as a link to that individual post) -
In that list of your posts, each post has a link to the board where you made the post at the top of the post., and at the end of the post there's the link to the specific post, responses are obviously after that.

On the site Menu (top LH of the page) you can click News and select "Your comments" where you'll find a list of all the most recent posts made to the site, each preceded with a link to that post on the relevant board (obviously if many other posts have been made, your particular post may have gone off the end of the list).

The specific post you made, and the reply you can find here - Get to see your Freeview predictions map | free and easy

Unfortunately, sometimes these links are broken. As the site owner hasn't had the time to fix them, we contributors have to make the best of it and it can be very frustrating, but in the case of the ones I've mentioned in relation to your recent posts, they all seem to work.

As it's a while back since last mentioned for this transmitter, some of the details at the top of the page are incorrect/not been updated recently. In the list dated 18th April 2018 - C32 & C34 are used for Local multiplexes.
COM8 on C56 has closed for commercial reasons, COM7 on C55 is still broadcasting and will continue to do so until at least sometime probably mid-2021 at the earliest (depending on MNO usage after the auction), but by 30th June 2022 at the latest according to the current OFCOM Licence.
