There is also the Maximum T85 which is larger than the T55 but smaller than the T90.
It doesn't have a huge front reflector, so it looks much less bulky.
It's also much cheaper than both, half the price O-Ha, which is an important point.
If you wanted the T55 for the Turkish channels on 7e, I think it may be too small, as the beams are around 48dBW and some Turkish channels are weak up here. For London a 70cm may be a sensible size in bad weather. Up here, an 80cm would be a better idea.
