Me: In answer to your question of 4:56AM, because different frequencies (and hence different signals) travel differently. The reason being that there are objects in and around them which refract, reflect and so on to degrees which differ by frequency.
The end result is that in one spot one channel can be good and the others not so. This was easier to see in the days of analogue, particularly if you ever used a set-top aerial. The trick was finding a spot for the aerial where all channels were good.
In response to your posting made at 12:52PM, I very much doubt you will be able to receive from Reigate. What makes you think that it's Reigate?
If you can receive from Rowridge then be aware that it uses all Group A channels, and that, as such, you would be much better off with a Group A yagi than a wideband yagi. See here for an explanation:
Rowridge Transmitter
With a yagi, the lower the frequency the less gain and hence the less directivity. A wideband yagi is a greater compromise than a Group one.
Rowridge's COMs are stronger vertically (it broadcasts all channels horizontally and vertically).

I think that I am receiving some signals from Reigate because I get a strong signal (strength and quality) on Channel 24 (498.00MHz).
Regarding the explanation of relections etc. that account for some channels appearing but others no appearing (same transmitter), I doubt that this is the reason because the frequencies are too similar and, therfore, the distorting effects are likely to be equivalent.

Me: Re: your 12.52PM posting, on what basis is the assumption being made that you are receiving a strong signal from Reigate? as the terrain indicator points to the signal from that transmitter being completely blocked starting from a distance of approximately 7.5 miles from your given location. (if genuine!)

Me: I think that if you are receiving anything on C24 then it must be PSB1 (BBC One etc) from Rowridge and certainly not COM5 (Pick TV etc) from Reigate.

I have been trying some different orientations of the aerial.
I pointed it towards Whitehawk Hill (WH) and received no signals. I adjusted the angles several time, but it made no difference. I tried a couple of heights, no difference.
I repositioned the aerial back to its original location, towards Newhaven. I can pick up weak signals from WH on occasions.
I assume that these signals are caused by refelections, although I am surprised that I can occasionally get signals from WH when pointing away from this transmitter, but nothing when I point towards it.
Can anyone suggest how I might increase reception from WH (home build solutions preferrrd, such as modifying the aerial).
On a related point, is there a difference between a Yagi aerial and an Antiference aerial.
Thanks

Me: Antiference is simply a brand name of an old established company who manufactures all types of aerials including the Yagi types mentioned.
With regards to the reason for picking up a signal from WH even although your aerial was facing the reverse, yes your assumption is quite correct as the signal from WH is obviously being reflected back towards you from a hill or some other tall structure, this type of thing is quite commonly experienced by many who reside in areas where hills can be seen in the background.
As far as improving your signal is concerned, its totally futile for anyone to try and improve the performance of a manufactured aerial as it quite simply cannot be done, because "if" by any remote chance any channel is improved it will always be at the expense of another.
That said though, the only aerial that can be doctored for a specific purpose is a Log periodic, although doctored in this case means killing part of its coverage range by removing two or three of the small elements on the front of the aerial to restrict its performance from Ch60 upwards in cases where interference from 4G might be a problem.
Matter of fact, in your type of situation a DM log used in conjunction with a 20db variable gain booster such as sold by Argos is a perfect combination for carrying out experiments.

Sometimes I get considerable reflections, at other times none at all. Since hills etc. are constant, am I right in assuming that the differences are due to atmospherics.
If atmospherics are the correct explanation for the difference in phenomena, I have noticed that similar weather conditions produce different results (strong or no reflections).
I find it difficult to explain these phenomena. I seem to get all (meaning weak), or nothing - nothing in between. The Signal, when I can detect it, is always strong, but of poor quality.
You mention experimenting with a log periodic. Would not removing the small elements (directors) from the front of a Yagi have a similar effect, i.e., reduce the forward gain. I would have thought that this loss would have resulted in a larger gain at other positions, including the rear.
I found that removing the reflectors, although in theory should have had an effect, had no effect at all.
Best wishes, thanks for the links

A log periodic aerial does not work in the same way as a Yagi pattern! Removing the directors of a Yagi does NOT improve the performance in part of the spectrum significantly, so it should not be done. It tends to reduce the overall gain, widens the reception angle and unbalances the reception across the designed operating band. These are most noticeable with weak signals. Removing directors behind the dipole changes the reception pattern so it is slightly less sensitive forward by more sensitive rearwards and sideways. The effect it to allow more unwanted signals to be received, which can easily cause co-channel or adjacent channel signals to interfere and for unwanted transmitter signals to be a potential source of trouble. You may well see a reduction in signal quality rather than any improvement! Aerial design always has an element of compromise but is not to be undertaken lightly without a full and comprehensive understanding of what is required.

Me: As MikeP has fully explained why the procedure mentioned for a log aerial cannot be used where Yagi's are involved then that somewhat saves me from having to, but as far as log types are concerned, the only reason that this can be done on a log is simply because that every element on a log aerial is active and with this being the reason for it being shaped as it is as, the short elements on the front of the aerial catering for the high channels and with the longer elements on the rear for the low, this totally unlike that found in any other aerial which only has one active element positioned immediately in front of the reflector.
The other point about a log aerial and its series of active elements being, that this arrangement results in the aerial having a relatively flat response across the entire band over that of any other type of aerial, and why signal levels measured across a main stations six mux channels when taken using a log aerial always results in a more accurate indication of the true level of the signal being received from each mux by the aerials response not enhancing any part of the band, (short logs being even more accurate) and why standard aerials are unsatisfactory for measuring comparative levels where accuracy is required.
Just purely out of curiosity, when you mention trying tests with your aerial in various orientations I was wondering what type of aerial you are using and where is it installed?
