Here are the story of Johan ON4IQ.

Assembly start.

It took several months after the delivery of the 43el yagis to get all assembled and mounted on the H frame.

Mounting 43 el on the boom was time consuming  even though there are just 2 screws for each element. It was straightforward though as each element was clearly marked and boom position was marked as well.

I didnt bother to check swr on each antenna as i felt confident in the build quality. 
Once all where mounted and connected with 1/2 inch hardline I swept the array with the analyser.
 
Swr is 1.004 to 1 at resonance 432.454Mhz
Swr is less than 1.1 to 1 from 432 to 433mhz
Swr is less than 1.2 from 430 to 439mhz
 
Needless to say i am very pleased with this.

Array is hughe, the only downside, it is well over 150kg, 12m booms, over 8m high. 
 
I have evaluated the array on tropo for 2 weeks now.
Boy it works, the OZ7IGY beacon at 746km almost always copyable.
A dozen of tropo qso made over 700km under flat condx.
Even one over 900km.
First the first time ever in 30 years some aurora qso.
 
It sure looks like a winner to me.
