Thats where a simple active homebrew combiner could be helpful instead of
wasting $600 on a fancy box. When they get down to $200 or someone else
duplicates the performance at that price Id be interested.

It makes difference on "regular" ground.
Once I put up "killer" 1200 ft Beverages on a location on the top of the
hill, with slightly sloping ground around. First night in the contest Inv
Vee was beating them. Sloping terrain and long wires were likely producing
low angles, way too low for propagation.
For the next night I cut the wires to half, 600 ft and they came to live,
what a difference!
Also at W8LRL QTH long phased JA Beverages compared to "regular" one were
hearing JAs while shorter one was "dead". At VE1ZZ lone single wire
Beverage, going down the hill and terminated in the SS hub cap in the salt
water was beating phased one on ground.
Depends on propagation, angles, more flexibility we have, more adaptable
we are to peculiarities of conditions. On good, salty grounds verticals
are kings and using arrays allows to shape the pattern to maximize the
signals and suppress noise and interference.

I actually tried this and discovered that any wire beyond
400 feet made no difference whatsoever. This is because
I am on high conductivity ground. YMMV.
