Nat;

First: The guys MUST be broken in non-resonant lengths to minimize
reduction in gain and F/B patterns.

Second; Series feed is highly recommended vs shunt; components in shunt
feed will not be identical due to tolerence variation and therefor
improper phase relationship (imbalance) is present.

Third: Spacing is 134 feet at 1.835. (Not 120'.)
