"Hi Rune,

I have one of these. Installed it in 2007 season but dismantled it at the
end of  season.
It just did not work for me on 160m, it had no directional properties and
was pretty deaf.
It wasn't faulty, worked OK on MW BC stations but not on TB.
Could have been due to the fact that it was sited only about 15 metres from
my Inv L?
Tried detuning the Vertical on receive cycles but it didn't help.

Physically it's a solid well made unit and Wellbrook were very helpful with
testing advice etc.

May work for you?

Good Luck es DX on 160m

Dave,

What is stated above has nothing to do with the new Wellbrook K9AY Phased 
Array Rune is referring too, as this product has only just been manufactured 
in past 3 months.

I can only assume that you are referring to a single K9AY antenna.

Btw, array gain is approx. -6dBi at 1.8MHz with 40m antenna spacing 
and -11dBi with 20m antenna spacing.
