Hi ya,
using a freeview box & still missing lots of chanels. spoke to someone from the tv company & they said that the chanels we were missing had low frequency (50,000w).
tried retuning but no luck.
the areial is on the roof, horizontal & doesn't seemed to haved in the wind.
any ideas?
cheers in advance!

James: You are located at only six miles away from the Rowridge transmitters and as such could be receiving an excessively high level of signal which can be saturating your TV or boxes tuner, try a test using either a set top aerial or a short piece of wire (about 12/18") inserted into the inner part of the aerial socket, then give the TV another auto-tune.
Although Rowridge is far more powerful on its vertically polarised transmissions than on horizontal, but at your distance from the transmitter this should be neither here nor there.

Dear Sir i have been picking up DTV VERY SATISFACTORY BUT SINCE THE HIGH WINDS WE HAD RECENTLY I HAVE LOST ALL RECEPTION COULD IT BE THAT THE ARIAL MIGHT HAVE MOVED OR IS THE TRANSMISSION BEEN HALTED,I LIVE IN PURBROOK JUST OVER PORTSDOWN HILL IN THE WATERLOOVILLE AREA.

hi, there are no issues with reception in your area, the problem must lie with your system, the only way to determine what is causing the problem is to do a system test, i am your local approved digital installer who can provide a free system test if you wish, please contact jays cabling services.
regards

Hi,
My postcode is PO38 2LE.
I can't get C28 (film4 etc).
I have tried both horizontal and vertical aerial position (high gain slx 48 is in the loft.) The main channels are all good strength signal and quality in both positions.
Any ideas please?

Colin: You should definately have your aerial vertical as the Commercial channels aren't as strong horizontally. The marked difference in strength can be an issue.
You may have too much signal, what with the transmitter being only five miles away:
Freeview news | ukfree.tv - independent free digital TV advice
The Rowridge mast can be seen in the photographs taken by Google Streetview on Chale Lane:
PO38 2LE - Google Maps
And Atherfield Road:
PO38 2LE - Google Maps
What's the reason for a high-gain aerial? Perhaps you should turn it the other way and point it at France!
If your aerial is a wideband one, which a look on the Philex site suggests that all SLx 48 models are, then it will have less gain at Group A channels, of which all of Rowridge's are.
There's no such thing as a high-gain wideband yagi aerial that has "high-gain" on Group A channels. See these curves:
Gain (curves), Again
Thus a high-gain wideband yagi aerial used on Group A channels isn't so high-gain.
As all Rowridge's channels are in Group A, where a high-gain aerial is needed, then it is best to go with a high-gain Group A aerial.
That said, why is a high-gain aerial required at only five miles with apparently good line of sight?

Colin -
you should try to locate the aerial in a different possition within the loft, sometimes simply moving the aerial a few feet either left or right can make all the difference.

Colin: If the problem is excessive signal, you may well have enough to distribute it to multiple rooms using an unpowered splitter:

Hi, and thanks to all for the replies.
We live in a dip in the landscape and there is a 40 foot hill directly at the back of the property so there is no direct view of the mast.
I tried a high gain aerial because the existing one didn't get C28 either,so a bit of trial and a lot of error...
I don't understand why the main channels are fine, but C28 doesn't get anything on vertical when the signal strength should be the same, if I am reading the info correctly.

Hello (again) all,
I posted the following just after the 18th April regarding the Rowridge retune.....
"I live in Poole, BH17 and have, since the 18th April, been having problems with Really, E4+1 and Dave. The picture stays for about 30s with approx 65% signal strength and 100% quality, then drops to 0% and 0% before repeating the cycle. I get this on my Sony TV and Sony PVR.
I have a wideband aerial (2yrs old) on a mast on the roof together with a 17db to 27db mast head amplifier. I have reduced the mast head amplifier to it's minimum 17db setting having read the signal may have been too high post switch over".
These TV channels are all on the COM5 mux (482Mhz). Anyway it was suggested that I try a YAGI 18A grouped aerial without the MHA. I've now have the YAGI 18a and have tried everything I can think of namely:
* YAGI 18A vertically and horizontally polarised.
* MHA fitted and not fitted.
* Aerial tilted up, down, left and right.
* Numerous retunes.
I have new PF100 cable fitted throughout.
The aerial is on a 2m pole on the roof pointing directly at Rowridge and yet I still get the total signal loss every 30ish seconds. It's as if something else is periodically transmitting on 482Mhz to interfere???
Can anyone suggest anything else to try as I'm close to losing it? Everything was fine prior to the 18th April.
Kindest regards,
DD
