UHF 2-m Parabolic + 8-El LPDA Feed
UHF 2-meter Diameter Parabolic with 8-Element Log Periodic Dipole Array (LPDA) Feed
analyzed using 4nec2.  Shortest LPDA Element to Parabola x=32.26452-inches.

Dimensions and 4nec2 file from GHZ24's website:
http://ghz24.freeshell.org/antenna/models/newermodels/parabolas

BTW: Based on trying different Feed Antennas with CM-4251 7-ft and 124-in (10.3-ft) Parabolics,
it is likely that a differentt Antenna will provide significantly higher Gain, esp. on lower Freqs.
