The computer models indicate that if you are feeding the L's in phase
(broadside) there is a slight advantage in having the L's point at each
other. This is theoretically .5db to 1.5db over all the other possible
permutations. I dont remember which permutation is the worse. This ONLY
applies in the BROADSIDE case. Other phasings have other optimal wire
placement.
My 1/2 wave spaced L's point at each other by luck of the available
organic antenna towers (trees) that I have to work with. My L's are set
up to switch in 180 degree of phase shift in one leg so I can go endfrie
as well.
For the sake of a few tenths of a db I wouldn't woryy about it a lot.
Put your time, worry and effort into the ground system.
