Colin: If your aerial is pointing to the Carmel transmiter, the frequency for ArqB which carries Film4 is now C49, as from 22nd May 2013.

Hello, ive just set up an 32 element wideband aerial + 4 way amplifier in my loft with the intentions of recieving wenvoe + all chans. Currently i am getting only those channels on 100MW. Does it just need tweaking or have i no chance getting the 50MW Channels here.

Many Thanks

I am receiving my signal from the Wenvoe transmitter. I live in the TA23 0RQ area. My reception of programs that use ch39 has all but disappeared. My TV shows signal strength of 5/10, and quality of 0/10.
Channel 39 transmission power is 50,000 watts, so is one of the lower power channels. ch45 is another low power channel, yet I receive this perfectly, strength is 8/10 and quality 9/10. I have a wideband aerial, digital grade coax and high quality connections/connectors. What is happening?

Derek Matravers: Perhaps the trees in the direction of Wenvoe are causing your difficulty.

Derek Matravers : A quick check on the terrain indicator reveals that the line-of-sight between the Wenvoe transmitter and your location is obstructed from just under 4 miles away, this (dependant on conditions) usually always resulting in erratic reception of one or more of the six mux channels used by the station at certain times of the year due to the fact that the signal is only reaching you in the first place by diffraction (bending), this frequently being responsible for receiving the muxes at slightly different strengths to each other as variables will always exist between the muxes even before they are subjected to bending.

Of course the trees as mentioned by Dave Lindsay making matters even worse.

jb38:
Thanks JB for your response. I know there are some trees in my line of sight to Wenvoe, but what puzzles me, is the fact that all the other channels from Wenvoe are ok (acceptable). This includes the other low powered channels. If it's a 'line of sight' issue, why are the other channels ok?

Derek Matravers: Don't ask why the one exception?

Instead, consider a single signal. It 'bends' (defracts) around an object, in this case the high ground over which you are receiving. The effect is that in the shadow of that object the signal isn't dispersed uniformly there are some good spots and some not-so-good spots.

The dispersal effect varies by frequency. Therefore each frequency will have its own "good spots" and "not-so-good spots". Hence there will be places where they are not all good at the same spot.

The same goes for refraction when signals pass through an object such as a tree.

The objective when siting an aerial is to put it in a spot where all channels are good. However, if the objects which cause the defraction (the hill, including anything on top of it such as trees) and the refraction (caused by the trees in front of the aerial) change/move then this could have implication on the signal(s) received.

Thanks Dave, for the explanation. That has made things clearer.
Seems like the only thing I can do, is to hope that channel 39 is moved to a more 'tree and hill friendly' frequency.

Hi, I live at SA2 9LR and my aerial uses the Wenvoe aerial.
Since a few weeks ago my Panasonic TV and Harddrive refuse to tune into Film4, Itv 4 etc, which I've received for years, they get BBC1, ITV1 etc fine. I can pick Film 4 up fine in the bedroom with our Samsung TV which shows a 50% signal.
My aerial (horizontal) is on the roof, pointing same direction as other houses, and uses a splitter/booster in the loft.
Any ideas as to why I can't receive Film 4 etc now would be much appreciated as Film 4 is one of my preferred channels.

Hi
I live in Brynithel Terrace.

Can I pick up a Wenvoe signal here?

At the moment an old tv arial I which is pointing towards a nearby hill top; I assume a 'reflector'.

I only have about 20 TV channels probably 6 are worth bothering with; no film 4, I have the basics and do manage ok. All the digital radio is on the tv as well, but I never used the tv for radio listening

I used to live in North Somerset where a tv scan is biased towards Wenvoe with Mendip signal also available in the 800's. Anyway I would like to have a larger choice of channels and I refer back to my initial question.

I am about to purchase a new tv aerial and if wenvoe signal possible here will mount the new aerial on top of the house rather than the corner wall where it is now (ie lower down) and pointing towards local small mast.

Think I have explained myself.

Thanks... Lee
