See all 'Engineer In Wonderland' postsI know my place, and realise that aerial design is not for me and must be left to those with pointy hats and wands.
So could one of those good folk tell me what this kind of aerial is and why it is better than the traditional Yagi-Uda or log-periodic.
They were spotted on many houses on the Canary Island of La Palma, all pointing east - possibly towards the larger island of Tenerife - and mostly pointing slightly upwards.

This is a DAT 75 aerial from Televes Pro. I also first noticed them in Spain a few years ago now but you can get them over here now from Maplin etc. The extra 2 sets of elements appear to give 2-3 dB extra gain over an equivalent normal single set of elements, or X shape elements.
Keep up the good work!

Well it appears to be a Labgear LAB450W: -

but even they don't tell you why it is better, but presumably the extra directors will work even if the vertical alignment is a bit out, as
stated in the article.
Televes make them too.
