To be frank, my immediate reaction was I'd prefer something with a variable gain control especially that close to the transmitter. You can have too much signal which can overload tuners and give problems with signal breakup.
Second, if you can find one in stock somewhere, those that I found were charging outrageous prices.
You could do better - a more flexible system, buying separate items. A separate log-periodic and find a 4 -way splitter with variable gain - for example I spotted this from B&Q of all places https://www.diy.com/depar….prd (assuming there is stock - not checked).
There are of course 6-way splitters, but again I'd want variable gain.

Colin Whatley: Thanks Chris. I was thinking I would need to amplify the signal to compensate for the signal loss because the aerial would be 8n the loft, but I guess I could test for signal loss before I buy by taking the Set top aerial into the loft and test for loss of signal. That at least should indicate whether I need to boost the signal before splitting, or just split.
I was thinking of that particular log periodic with incorporated 4 way amp, because it is part of a kit from TLC, including mounting kit, for an offer price of 32, which I think is a good price, don't you!?

Yes I guess 32 is probably quite reasonable, the prices I was seeing elsewhere were considerably more., but what's the delivery cost with TLC (I haven't checked)?
You will need to amplify it a bit to make up for the losses with a loft aerial and splitting it that many ways but it's very much a case of how much and it could be easy to overdo it, but if you can get the kit cheap enough you could always add some attenuation.
I did see one bargain price at Toolstation if you have a branch near you that has one for click and collect, as it's not available for delivery SLx Megaboost Aerial Kit 4 Way it's a clearance price of 15.61, even I would have bought one at that price if any store near me had one!
Whoever you buy from, don't forget metal coax plugs, and any double screened coax you need.
Even though you may not need it although I think you might, I would still buy this variable attenuator Satellite or Cable TV Variable 0-20dB Signal Attenuator F Type with Short Cable 5060507532225 | eBay (that's ebay item 253378790228) it is exceptional value coming with that short cable. It has the advantage it's DC pass-through so you can put it anywhere in the system. If you were to find that all outputs need attenuation, you might get away with this between the aerial and the splitter.
I'm assuming that the outputs you are thinking of splitting so you have 6 in all, will be the ones for the shortest cable runs, in which case I think I'd get a couple of the cheap plastic Y splitters as their insertion loss will provide some attenuation that you'll likely need. They are so cheap (eg. TLC 66p ?), if it were to turn out you needed the metal low loss splitters instead, it's hardly a big waste of money!
In any event, I'd start experimenting with the attenuator at your main set where you'll presumably site the PSU (at least to experiment). When you have some idea about how much attenuation might be needed you can then think about where you put it and also the PSU as you'll want the splitter powered up even when the main set is not in use?

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?

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.
