I was hoping for any clues as to why the BBCA mux is not receivable on an indoor aerial (43db gain) whereas the other Mux's are fine.

Is the transmitter array for BBCA lower down the mast for instance?

Barry: With knowledge of your location why on earth do you think this might be a weaker signal???!!!

The terrain plot suggests you have clear line-of-sight at 7.6 miles. The transmitter is 100kW on all channels!

Your problem could be that the signal is too strong and that "the right angle" is one where the strength is a little lower.

As for an antenna that has 43dB gain, I doubt there is such a thing. The claim is presumably one put there by marketeers and applies to a device which combines an antenna and amplifier (which as a whole is referred to as an "aerial").

If this has a variable amplifier then I would start by turning it down to minimum and work from there.

Providing it is sited in a room with good quality reception, which is preferably with as few a walls in the way in the direction of the transmitter as possible, then something like this should be suitable:

SLx Indoor Digital Aerial ANR310 UHF DAB Fully Flexible Caravan Motorhome | eBay

I have one of these and received digital television before switchover, when the transmission power was lower than now. I am 25 miles from Emley Moor with a relatively clear signal path (the top of the tower being visible above the horizon from a nearby railway bridge) and the signals were radiated at 20kW.

The only mux that is a problem is BBCA. It would seem that there is line of sight to the transmitter. I am at a loss as to why the one mux is being received at a lower level than all the rest.
I have tried the amp at minimum and another indoor aerial with a lower claimed gain.

Barry : Purely with reference to your question regarding the TX aerial mast, the PSB transmission aerials (panels) are always located at the top of the mast and as such can sometimes be received in a not too distant location at a "slightly" lower strength than that of the other transmitters radiating from lower down the mast, the signal "over the head" effect being totally dependant on the terrain, and of course with the reverse situation sometimes being the case if the receiving aerial is located on high ground.

Barry: Different frequencies travel differently which explains why all signals broadcast from the same place and at the same power can be received at different levels.

As jb38 says, you could potentially be affected by the "umbrella effect". This is where the high power transmitter focuses the beam further away - which is towards its horizon. This is opposed to focusing on the ground closer to it.

If you can then use the loft aerial. This may provide more stable reception anyway.

Most main transmitter sites use 'trapezoid slot' aerials which are positioned around the cylindrical sleeve (weather protection) so radiate equally in all directions. A typical aerial array has a number of such slots around the circumference and stacked in a slightly staggered pattern to ensure equal radiation in all directions. Each slot aerial radiates *all* the signals for *all* the multiplexes so there is not significant difference in radiate pattern or power density.
It does differ on the smaller 'repeater' or 'freeview light' transmitters as they are required to me more directional.

MikeP: That's interesting because the aerial heights given for PSB channels and COM channels of some of the high-power transmitters are different where they are all at the same power, e.g. Emley Moor. The latter is usually slightly lower down.

I'd read into this that there are two different arrays, perhaps with the latter having the beam tilted lower than the latter. (I note that all six of Winter Hill's are 726m. Sutton Coldfield's are all the same.)

The main transmitters where the COMs run at half power to the PSBs generally have all six muxes at the same height which would suggest that they all use the same array, presumably because the additional cost of a second array isn't seen as worthwhile and that reducing the power is a more economical way of reducing the coverage footprint (so as to reuse the channels).

Hello.

I'm experiencing an odd problem on Freeview HD channels only.

On HD, there's an occasional black flash on the picture, almost as if someone walked in front of the camera. Sound is uninterrupted.

There can be no problem for a while, then these flashes will occur several times a minute.

Any clues as to where to look?

Thanks.

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
