Ch50 HD reception has been a problem from day one at this location,and I believe interference from Wales may be the cause.
The aerial is group B/V,line of sight(I can literally see IOM.)SD Ch43 and 46 100% sig.strength and quality.Have moved aerial several times,tried attenuation,mast head amps etc.At present aerial is panned about 5 degrees North west of Tx and no amp in use.
Best results so far,but HD still weak ,and no or little sig quality.
RTE coming in full strength from 3 Rock on Ch 54 DVB-T,and HD.

Tony Mallon: Newry (as in Armagh?) could be receiving UHF Ch.50 from Presely, but this would be H-pol.
RTE from 3 Rock is also H-pol (though why you'd be using 3 Rock rather than the V-pol Clermont Carn Tx isn't clear).
The SD channels from Presely are also on UHF 43 & 46, so are using the same frequencies as Beary Park, but so are several other relays on the IOM (Port St. Mary, Union Mills, Laxey, Ramsey, Jurby. All V-pol. apart from Ramsey).
Would it be any better if you tried an H-pol aerial pointing at Presely?

Newry

Thanks JmF for taking an interest.
Postcode for some reason is Newry,actual location is Analong.I am told on Boards.ie that Clarmont Carn will be blocked in a Northerly direction until UK DSO,and I find Ch,53 CD/V quite so.
Any signals from Wales seem to be greatly dependent on prop/trop conditions,and would drive you quite mad.
Have been banging on about the IOM difficulties since S/O back in Oct.I think,and the subject was well discussed on "Help with Freeview across the sea in S.Down.Have tried many interesting suggestions ,but to no avail,some work carried out back in May at the Tx made things worse from this perspective.
Have had no problems with DVB-T from 3 rock or Kippure on Ch 54 c/d /H,seems a more robust system of transmission than UK Freeview HD,with its interference problems?

Hi Tony: Analong (Annalong?) would be a much better location for receiving telly from Beary Peark. The radiation pattern seems to give full power in your direction (the Port St. Mary Tx puts out very little your way).
It does appear that you are exploring the tolerance of transmission formats to co-channel interference. Trouble is that there are a lot of contenders for co-channel signals on 43, 46 and 50:
Chatton (more northerly than Beary Peark),
Emley Moor (slightly south of BP),
Llanddona (on Anglesey, south-east),
and Sutton Coldfield (analogue, almost in line behind Llanddona).
From your comment about getting best results with the aerial pointing slightly north of BP, I'd suspect Emley Moor.
A very directional aerial might improve the situation - probably need to have a narrower beamwidth than a single log periodic by using two horizontally spaced logs and a phase matched combiner (Vision Stealth kind of arrangement).

Thanks for the info,best IOM HD sig.yet,today C/N 43 ish.Seems to be stable,but we have been here before,only to loose everything just before the credits roll.
RTE 3 Rock or Kippure romping in on Ch.58 with HD and "future" test cards,radio and HD images.No amp required from this location.
Nothing from C/Carn I am told until 2012,alas,although I picked up Cairn Hill RTE HD in Castlewellan.Not reliable but interesting on a Tesco STB for £30.

Hi Jm F
Took your advice and a Log periodic has much improved things here.The fact that it comes with a very large deflector seems to improve C/N.Guess the interference on Ch50 is coming from the rear.Thanks.

Tony: Good point about interference possibly coming from behind the aerial - I've not (yet) got all the details for Irish transmitters to factor that in. I'm trying to think of a log periodic aerial with a large "deflector" though - which one did you get?

Slightly embarresed to relate I was in Macro in Belfast,and picked up a "One for All?"Think its Log?
Aerial,clamps ,lots of good co-ax,for £20.
Also found two STB at £10 each!
They are similar to the Tesco Tecknica box and work on BBC anfd RTE HD (DVB T and T2)
Am just checking the IOM Ch 50 Sig and it seems to have improved remarkably,but for how long?.I am line of sight almost with RTE Tx at Carlingford,Clarmont Carn Ch 53 V.
But it is, we are told severly nulled to the North until UK DSO.More likely to be interference from Wales?

Tony: Both the "One For All" aerials (SV9352 single boom and SV9355 triple boom) are Yagis not log periodic. Log periodics don't have the large reflectors at the back, so have low wind loading, but also have less gain. The particular advantage of the logs is that they're more directional, and two working together can be arranged to give good rejection of an unwanted transmitter.
Based on your location though, gain will also be important so if the new aerial works then carry on with it.
That does look like a good price for a T2 capable box!

Thank you for putting me right on the Log Periodic front.I have a log band 111 on Dab,works well N and S.
Sig strength at this local,no problem on IOM (can see it out the window.
The Deflectors make a big difference on the 1 for all,best so far ,without going to more expence for the friend who lives here.
Have been at this DVB-T2 ,HD reception interference prob since IOM s/o back in Oct.
Getting there,but no doubt more fun ahead for all in N.Ireland rural areas.Thanks again.
