I forgot to say currently Oxford aerial is separated from London so have 2 separated feeds. the main house have BBC south and ITV South.. while i have ITV an BBC London in my workshop and my bedroom... I am a TV repair man... i did ask local aerial guy to have a look... he refused point blank as my house is 3 stories high...... same for my old sky dish that desperately needs new LNB its been up there since 1999

rob: See the following terrain plots:

Crystal Palace:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


Oxford:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


Hannington:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


As you probably know, none are sparkling owing to the fact that you are surrounded by high ground.

Due to the dog's dinner of aerial groupings from transmitters, using a diplexer to combine feeds from different transmitters is becoming increasingly impossible without loosing access to some channels.

However, Crystal Palace and Hannington are about the only pair whose channel groupings which aren't overlapping, almost.

I say "almost" because COM7 and the forthcoming COM8, if receivable by you, overlap from these two transmitters. "If" you can receive all channels from Crystal Palace you can add Hannington for BBC and ITV using a diplexer. This would mean you would only be able to receive COM7 and COM8 from CP.

The only warning is that PSB3 from Hannington is on C39, so a C38 diplexer would attenuate it a bit. If you use a C36 diplexer you would attenuate COM8 on C35, when is comes on air from CP. At the present time, however, BBC One HD on PSB3 is the same for all areas. ITV HD has about four or five regions nationwide.

Don't use your tri-boom for CP:

I have done abit of Research but correct me if i am wrong.... I saw on Blake areial website... I have decided to buy some decent areials.. will get DMX10 Group A for London.... And is it worth me buying a group B for Hannington same type of aerial...

because i found wideband areials are prone to picking up unwanted interference.. the new areials will have LTE filters built in them.

I like your opinion on this Dave Lindsay.

thanks for your time :-)

rob: I write on here as a technical bod rather than an aerial installer.

If you're going to use a C36 or C38 diplexer to combine the two feeds, then the LTE filter only need go on the Hannington aerial because by definition C61 to C69 (which are allocated to 4G) is filtered anyway. Or, feed the two aerials into the diplexer and fit the filter afterwards, I wouldn't think it matters. The main thing is to have as much as possible in the loft so as to facilitate easy access, should there be a fault or should you find that the solution you have enacted requires adjustment.

ATV in Sheffield's website gives lots of information www.aerialsandtv.com They sell stuff too obviously other retailers are available. ATV sells Blake stuff and from what I've read Blake produces very respectable products.

The saying is "if you can use a log, use a log". A log periodic is wideband and therefore will work on any transmitter and even so when the powers that be decide to play musical chairs with UHF channels and groupings.

The gain of an aerial is at the expense of acceptance angle. Or to put it another way, think of the aerial as if it were transmitting (rather than receiving). The higher gain aerial would be radiating a stronger and narrower beam. Thus, thinking back to the aerial being used for receiving, where you don't have line-of-sight to "see" you have no real beam from the transmitter so it could be said that a wider angle might be better. This is because the objective is to get good quality and the quality over a small angle could fluctuate whereas over a wider angle the average quality is more likely to be more stable. You can always increase strength with a signal amplifier, something which it is inevitable you will have to install anyway.

So, I'm not sure under what circumstances the Group A and Group B yagi aerials you mention might be better than two logs.

One possibility is to get one log and try it on each transmitter, in turn, giving a period of several days maybe for evaluation. That said, obviously where you don't have line-of-sight as is the case for all three transmitters, reception could vary at different times owing to things on the ground such as trees which have leaves on in summer but then you've got that irrespective of which aerial(s) you go for.

rob : Apart from that said by Dave Lindsay with regards to the narrow pick up properties of using the aerial you have mentioned, another downside of using a high gain, likewise highly focused, aerial in an iffy non line-of-sight situation is that the signal received has the potential to suffer from what's known as the "summer / winter" effect whereby the strength of the signal drops off as the season changes, these changes having an effect on the reflective properties of the terrains surface which can result in the aerial receiving the signal from a "slightly" (and only slightly) different angle, hence the reason for the drop off.

Situations like this are easily rectified by turning the aerial a few degrees to the left or right to re-peak the signal, but though this action can only be classed as being temporary for obvious reasons, i:e: it will require realignment again at a later date.

Of course, that said applies more to situations where the signal received is of a reasonably stable nature without it frequently suffering from rapidly occurring changes in quality, that is if "not" presently using a high gain aerial, as using one will certainly "not" help the situation but make it worse.

Thanks Dave and jb38.

I will later when the weather is warmer... I just Buy Group A solely for London. keep the tri boom for southern... will try a Log aerial in my loft... its massive loft. I have already plumbed the electrics and Each aerial has its own mast head of 26.dB and power pack all Lab-gear stuff. The tri-boom is a lab-gear works well with Hannington in the loft got 90% signal and 100 quality BUT... channel 44 is the only one is showing 50-60% sometimes break up on Dave,pick and some shopping channels..... I think that will improve when i install it outside... I don't like using aerials in the loft as you loose a bit of gain. I shall install them in spring... all the wiring goes to the loft. just to make the masthead,combiners accessible as i live in 3 story house. the amps are 5 meters apart.... Yes i have followed the lab-gears info....
Since i used the tri boom on Hannington.... the picture has improved not so blocky and subtitles have stopped dropping out and disappearing all together. so i must be doing something right.... at the moment its trial and error. My area is god awful for tv reception for years. I have noticed in my Villiage of Purley-on-Thames allot of the aerials pointing to CP with 10 to 15 ft mast and mastheads. I have seen one tri boom the largest one you can buy.... pointing to London on 15ft mast... i thought NOOOO should be a group A for better gain... the guy told me oh that's a decent digital aerial cost him £400 to have it installed with loft amp and 5 TV points...But no such thing as a "digital" aerial.. got a feeling he have been conned

anyways that's another story..... will keep you all informed in end of March-April depends on the weather...

My Local Aerial dealer SAS of Beenham told me that Log areials are not suitable in my area... told me only usefull for strong and medium areas... my area is poor/ fringe area

He might be wrong.... i do prefer Log aerials as less wind load and looks much tidier

So what you say dave is he wrong??? am looking to get Triax Log 28

rob: I wouldn't say he's wrong I'm not an installer so wouldn't like to say categorically either way.

The principle is that you can improve strength by amplifying. You can't improve quality by amplification quality starts and ends at the aerial.

So if the log is seen as not suitable because it doesn't have enough gain (to provide to one receiver on an average length of cable) then one could say "it's not suitable". Also, a high(er) gain aerial isn't necessarily a suitable alternative to a lower gain one used in conjunction with an amplifier.

As you are using an amplifier (because you want to supply multiple points and because of cable length due to the height of your house) then perhaps signal level from the aerial isn't so much an issue.

jb38 can you confirm whether I'm on the right lines or not?

Dave Lindsay: Well, although a group aerial can undeniably give a slightly stronger signal to that obtained from a Log aerial, and a booster fitted onto a high gain aerial will indeed give an even stronger signal, but though when taking into account that mentioned in my previous posting regarding the possible downsides connected with using a high gain aerial, plus another I forgot to mention of a viewer experiencing a much higher incidence of picture glitching, I would "not" recommend using anything other than a Log in situations such as Rob's.

I have never at any time experienced a situation where a yagi type multi element aerial actually picked up a signal that a log aerial (even minus a booster) didn't, and a suitably positioned (through experimenting) Log aerial used in conjunction with a good quality high gain booster such as Rob's mast head devices, really does take a bit of beating.

And so the answer to your question is basically yes!!
