You might want to try investing in a Televes DAT HD Antenna (wideband) with passive/active inbuilt pre-amp. It is a most sensitive unit and works superbly in fringe areas /poor reception zones, in active mode the aerial gives somewhere in the region of 26dB gain which will help overcome any losses on downlead and loss created by LTE800 4/5G filters. You will need a 12VDC PSU / mast head type PSU to power the pre-amp.
This setup works fine for me and I'm 40+km away from Sutton Coldfield in a rubbish reception zone.

The Televes DAT 45 HD is not to be confused with the Televes DAT 75 which is a beast of an aerial.
The purpose of recommending the wideband Televes DAT45-HD is that it has a wide receiving angle, high sensitivity and an integrated intelligent pre-amp and as such is superior in operation to some cheapo Yagi wideband with a masthead amp. An obvious choice for use in fringe or poor reception areas and in lofts.
Wind resistance is not an issue as my set-up is in the loft / roof space and delivers a high quality 69dB signal with the preamp active, plus the inbuilt pre-amp reduces cable connections from 3 to 1 which is never a bad thing.
However, I do take you point about low wind resistance antenna for external installations e.g. log periodic, but this is not the case here.
A prievious post by 'Roy' highlighting his disappointment with his new loft aerial quote,
" Yes I was fully aware a loft aerial was less sensitive than a roof one, it was a cheap gamble, although if they work they're spared the weathering and wind blowing them over the years, sunlight cracking the coaxial, water penetration, birds sitting etc. I'd hoped a modern aerial might outweigh the loss of sensitivity from being behind the tiles. So far it hasn't, though it might as you say perform better in future".
Aerials are not an exact science in application, more a 'dark-art'.
May be Roy should try a Televes DAT 45 HD as it could negate the effect of signal attentuation caused by the roof cladding and provide the reception improvement he was looking for.

Richard:
Your TV / Freeview receiver / recorder may have been obsoleted due to the changes requiring the receiving device to be compatible with T2 transmissions.
