Hi Jerry

Very good question ,and I do not have any information regarding their
comparison.

On this tower due to the size and isolation I would have to split the
feeder and have a minumum of two or more antennas around the tower .
(Toer is 10m in diameter with steel reinforcing - high front to back
isolation)

For this specific case , a Lindenbald would perhaps have too much
horizontal space to mount a number of them around the tower.

Unless you are assuming that one uses one antenna split over the 4 ,
equally spaced around the tower.
Again this is a good question as under normal circumstances one does
not have the high isolation between the elements .

I could use a 1:4 wilkoson and mount folded dipoles at skewed angles ,
so at any one time a distant station should see at least two of the
4 .

This is a lot to ponder about .
