This evening's transmissions started at 17:30 and were rather unprofessional in broadcasting quality terms.
The station seems to have started transmissions (after considerable delay) before it was really ready.
Hopefully it will get better?

I have lost itv and e4 and a few others.
i have 2 aerials serving 2 tvs and they have both lost the same programs.
one aerial is indoors and the other is outside so there must be a fault in the transmitter.................

robbie mullaney: ITV, ITV2, E4 and others are carried on PSB2 multiplex. Oxford broadcasts this on UHF channel 60, which is the highest and the closest to 4G services in the 800MHz band which may be operating in your area, these occupying channel 61 upwards. The mobile base stations which are a short distance from you are also in line with your aerial too.
Therefore, it's worth seeing if 800MHz 4G has started by ringing at800. at800 is the company set-up by the mobile operators and tasked with alleviation of reception issues:
Contact us | Advice or general enquiries | at800
There are mobile base stations a short distance away.

robbie mullaney: It sounds like a stupid question, but are the two aerial systems entirely seperate, and are you sure that the TV's are being fed independently?

This Week has been very bad for Freeview TV reception..... due to change of weather condition's... It did affect Hannington, Oxford also London via Crystal Palace. Best thing to do is to ride it out and DON'T adjust anything to your TV and aerial. In old days of co channel interferance there used to be a BBC and ITV transmitter announcements saying due to weather conditions please do not adjust your tv set. Shame we don't see or hear of this anymore.
I remember many years ago.. that Digital TV will not be affected to poor weather and no interference..... wish this were true.. but science and theory does not apply to terrestrial transmissions and receiving.
This also applies to SKY / freesat mini dishes... when it rains lose the signal.... the mini dish might look pretty and neat.. but no good in heavy rains... i have recently installed a standard 80cm dish OK it might be bigger but very reliable satellite signal in any weather.... best to use solid dish and polish it with car wax polish every 6 months then any water hit the dish just rolls off.... it works for me.. hope this tip helps.

Poor weather affects satellite TV due to rain attenuation at microwave frequencies. However, although high atmospheric pressure can cause tropospheric ducting and reception of UHF at extreme ranges, probably the only significant effect of poor weather / heavy rain is due to moisture ingress in poorly insulated TV antenna systems.
BSB was far less affected by heavy rain than analogue Sky TV, due in part to slightly higher transmission frequencies but also higher power and DMAC modulation. Sky Digital is much more resilient (as far as the viewer is concerned) and the 'sparklies' which used to plague analogue satellite TV aren't a factor - only in severe weather, when the signal drops completely, are you likely to lose Sky.

Whether you use a solid or perforated dish makes not the slightest difference to the way it reflects the microwave signals onto the input horn of the LNB. A perforated dish has the advantage of allowing airflow through, so reducing the wind loading that can cause mis-alignment plus they tend to be a little lighter so reducing the load on the mountings. The holes/perforations are too small to affect the ability to reflect the signals onto the LNB. Having a clean surface that repels water is a good idea though. The key factors on how efficient dishes are is largely determined by the effective diameter of the said dish, a larger surface area 'collecting' more signal to be reflected, and how well the surface curvature is formed to focus accurately into the LNB horn. All the advice on dish size is based on using a conventional perforated dish and would be identical if you used a non-perforated dish. You can work it out if you understand spherical geometry at microwave wavelengths.

Rob: Mike I have been using satellite television since 1989.... so i DO know what improves the reception of satlitte TV also the lower noise LNB I.E 0.2dB helps... the SKY mini dish is really an gimmick for sky and i had alots of problems with them due to heavy rains in the past..... the mini dish is far too small.....
so don't tell me that i am talking rubbish!

I wrote the original installation and service manuals for both the dishes and set top boxes needed for Astra reception in 1988 and 1989 and subsequently those for BSB Squarials and receivers. As a senior technical trainer and manager, I too know what I'm talking about, especially as part of my thesis was on satellite receiving and transmission systems. (But I chose not to use my full title on these pages.)
