[K3CAL] 2 meter/70 cm Log Periodic Antenna Project...

[Rich Weaver]

Log Periodic Beam Antenna that covers 142 - 450 MHz continuously....and with Gain
What’s the purpose of the log periodic other than for a scanner? 
We can’t transmit on the entire range.
How much gain? Is that in DBi or DBd?
If you are going to use it on 2 meters, then build a 2 meter yagi.
If you are going to use it on 70cm then build a 70cm  yagi. 
Why waste all the extra elements that are not in the ham band?
Better yet build a 2 meter yagi with a 70cm yagi under it on the same boom.
