I think it is an interesting mail, so I copy it back in the mailing list. On 5/2/07, Tobias Stoeber <tobi@xxxxxxxx> wrote:
Regarding the "One For All" Aerial it seems, that it can be positioned either vertically or horizontally. So you should first try to (if you didn't already) to get to know, which polarisation the signal from your dvb-t station has. Make sure it's placed right, e.g. if its horizontally polarised it should be like in the small picture, if its vertically polarized it should be like in the large picture.
I live in London, and I get signal from Crystal Palace, and I had better results with the horizontal position.
Next I would try different location within the flat. Your aerial has a 20 dB amplifier. Unfortunately, if the original signal is bad / has much noise, a more powerful amplifier will not be of much help (you will just amplify the noise/interference as much a the signal itself).
I think it is the case. Someone in the building mentioned that there is an iron structure that kills all signals. People at the lower floors have problems to tune a radio. Thanks for the info about the aerial. I'll try to understand better your message. It looks to me that there are different shapes, the one in your picture looks VERY different than the One For All, and the ones your linked from Amazon. Do you recommend a compact one (maybe more elegant) or a trditional shape? Or it does not matter?
For some testing I would buy (or try to borrow) an large outdoor aerial and search for positions, where I would get I good signal. Then I would try to use an indoor or small outdoor aerial. I mysqlf use both an self-built log.-periodic dipole antenna/aerial (LPDA) and a small indoor aerial. A picture of the LPDA you'll find here (if my home server is online/working ;) - usually during working hours) http://www.extern.softclick-it.de/~tobi/public/tmp/dvbt/dvb-t-lpda-1-det.jpg http://www.extern.softclick-it.de/~tobi/public/tmp/dvbt/dvb-t-lpda-1.jpg The indoor antenna I bought was about 10 Euro (~7 £) and is a THOMSON ANT D220. I can really recommend it (but my LPDA is still a little bit better, but also larger [length 96 cm, height 32 cm]). In a test report (here in Germany from "Stiftung Warentest") your aerial scored 12th place out of 20 aerials, with resonable but not good reception (antenna gain). The Thomson got 3rd place (lost some points because it has some problems when mounted somewhere without screws due to it's thick cable - I just replaced it). Placed on 1st place was "Hirschmann Zifa D-16", 2nd "Philips SBC TT350".
Thanks for the info. I've found a cheap 2nd hand of the Philips. I will try it.
Maybe you can also have a look at the follwing models (sorry for the link from amazon.de in German): AXING 1603 with 25-27 dB amplifier http://www.amazon.de/Axing-Flachantenne-Zimmerantenne-geeignet-Verst%C3%A4rker/dp/B000KU1FJ0/ref=sr_1_23/302-4850549-8840012?ie=UTF8&s=ce-de&qid=1178060712&sr=8-23 Kathrein BZD 40 http://www.amazon.de/Kathrein-BZD-DVB-T-Outdoor-Antenne/dp/B000KPPXIO/ref=sr_1_43/302-4850549-8840012?ie=UTF8&s=ce-de&qid=1178060729&sr=8-43 Well, good luck!
