4 elements Quagi antenna for 50 Mhz
This is an interesting quagi antenna plan.
Total Boom Lenght is 3 m.
Original design By Roberto Turco

You could add at least some performance data… OK, here you are my NEC2 simulation results (I used copper conductivity for the 1.3mm wire and aluminum for the two directors):
Resonance 50.8 MHz, SWR 1.57, Forward Horizontal gain 10.01dBi, efficiency 99.2%.
One of the main benefit of the Quagi design is to provide nearly 50 ohm impedence @ resonance, this design does not provide such a benefit –> needs matching network, otherwise ERP is dramatically reduced. BTW, the secondary lobes are sligthly backward oriented.
