DBGH Wide Beamwidth/Omni Investigations

DBGH Wide Beamwidth Investigations (e.g. 60+degrees or multi-lobed), including higher Gain Omnidirectional antennas analyzed using 4nec2.
In response to Vorg's situation in Tucson, AZ with THREE widely separated tower groups.

Includes the following DBGH versions:
a. 300ohm-X0429, mod by 300ohm to wildwillies X0418-Mod0 (No Reflectors): Six Lobes, beamwidth varies with frequency.
b. XA-X0433, mod by XAuto to wildwillies X0418-Mod0 (No Reflectors): 2 Very Fat and 2 Narrow Beamwidth Lobes.
c. WW-X0442, wildwillies: 2 Fat and 1 Narrow Beamwidth Lobes.
d. WW-X0450 (aka WW-X0442 Rev3) by wildwillie: Quasi-Omni-Directional.
