NOTE: the lengths of the 0.750" o.d. sections have been reduced by the lengths
of the 2.4053" o.d. sections which simulate 5" x 6" x 0.375" plates.
These elements are heavy-duty (120 mph).
This design was optimised for F/R over band > 29dB, & SWR <1.8:1, with a
mid-band free space gain of 13.25dBi (11.11dBd).
MATCHING: 2x75 ohm parallel coaxial cable, LENGTH 1/4 LAMBDA (99 cm.RG9 or
RG11) for R.O.S. 1:1
