Has anyone got any tips on what type of aerial would be best to use, am located in Worle, postcode bs226lj, and currently have issues with fluctuating signal quality on numerous channels, strength is stable and high, around 90-95 percent that's with using a booster which I don't think I should need one with an outdoor aerial but without the booster the fluctuating signal quality is even more of an issue so the fluctuating quality isn't directly related to using a booster. I do know about the pros and cons about using boosters so be need to really go into that, it's the types of aerial I'm interested in getting advice about.

We do have a main road outside the house, the fluctuating quality is a lot to do with traffic as the issue goes away late at night, early hours of the morning when there's obviously hardly any traffic going by. My location isn't on one of the high spots around Worle so the aerial doesn't have a direct line of sight but I don't think that's the issue with the quality fluctuating due to the situation improving late at night etc as the tall trees (not close by but are in line with the direction the aerial is pointing) are there all the time lol.

I'm sure I've seen an aerial advertised that is supposed to help with interference issues but can't recall if I'm correct on that one, the one we have on the roof now was installed a few years ago, the installer said it was good enough but it looks like the one of the old aerials that have been around 20 plus years, if you know what I mean.. The cable being used with the outdoor aerial is pf100.

Paul: Locations where the quality of the signal received is being adversely affected by traffic passing along a nearby roadway, can in "some" cases be down to the aerial having moved slightly whilst it was being tightened up, insomuch is sitting a few degrees to the right or left of the exact direction that the signal is coming, this type of thing making it more sensitive to such as reflections from passing traffic etc, multi-element aerials of the high gain variety (should this apply) exacerbating the problem because of their narrower signal acceptance angle.

Therefore, as the aforementioned is only one possible reason for your problem, it would be rather prudent to make one or two local enquiries to ascertain if others are also suffering from similar problems with their reception, because if they are, then your aerial alignment is likely to be OK.

That said, you are indicated as being at 15 miles away from the Mendip transmitter @ 124 degrees, the line-of-sight problem you refer to seen on the terrain indicator as being at 7 miles prior to your location, a factor related to this being that reception of signals of a non-direct line nature is only possible through what's known as diffraction (signal bending) resulting in them being more vulnerable to anything that might interfere with them, e.g: such as vegetation in the form of trees etc on the land that is causing the LOS obstruction, this unfortunately being something that no one can do anything about.

By the way, on the subject of aerials, its quite unnecessary to use anything other than a Log periodic (Log 36) aerial for DTT reception, their only problem being one of image, insomuch that people incorrectly equate large pieces of metalwork on their roofs as in some way being superior to that of the much smaller Log types, the latter in many cases giving a superior level of glitch free reception by having a wider pick up angle plus a near to flat response across the channels.

Hi All,
I cannot seem to find any mention of current Freeview interference on ITV and C4 variants for the Mendip transmission area. I live in the Taunton area and although we appear to be on the edge of the coverage area we normally have good reception. The picture/sound have been blocking for a couple of weeks now, making viewing and recording impossible. I don't think it is equipment because both the TV and digibox recorder have the same problem. Has anyone else had this problem and are there any solutions?
Thanks.
