Phil Alcock.Pleased that the problem that you had has now been alleviated by switching aerial polarity from horizontal to vertical especially concerning the commercial SDN,ArqA and ArqB multiplexes on Rowridge.

Hi
During the past week reception from ITV1, C4 etc has been eratic - no signal daytime, a bit better at night. Was originally OK but, despite re-tuning, now not good. Could this be due to sunspot activity? Aerial is clear of roof ridge and points same direction as neighbours aerials. Aerial is high-gain & has preamp on-board. Is this a polarisation problem? 4th May 2012

R W Penny,Arundel.Is your aerial horizontal or vertical polarisation and if so is it a group A type (tipped red) or a group W wideband type (tipped black).Polarisation could be a problem,but so could the preamp you mentioned on board as well as the aerial being a group W wideband type some 60 odd miles from your location to Rowridge,and possibly the condition of both your aerial co-ax cable and co-ax aerial plug too.If you leave a full post code preferably to ascertain the possibility of a single frequency interference issue on frequency 27 in your location,the D3+4 multiplex on Rowridge you claim has been erratic just recently,or possible inversion but highly unlikely then further assistance will be available to you.

steve hooper: I think that the likely answer is yes.
The problem you have is probably due to the difference in strength of the Commercial channels relative to the Public Service ones. The Commercial channels are, after all, 50kW horizontally, which is stronger than some smaller main stations.
The higher power signals could be acting to desensitise your receiver making it more difficult to pick up the (relatively speaking) weaker ones.
You "may" be able to attenuate (all signals) and find a sweet spot where all will work fine, without the need to adjust your aerial. A variable attenuator allows adjustment, and these are usually (up to) 20dB. If you do try this, 20dB might not be enough, judging by your close proximity to the transmitter. You may need another attenuator, say 18dB or 24dB, and have this connected inline with the variable one.
See: Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice
Attenuators are available for a few pounds from sources such as eBay and Amazon.
