This is an interesting quagi antenna plan.
Total Boom Lenght is 3 m.
Original design By Roberto Turco

Hy Roberto,
Y try to make thus Antenna……….Looks very good !

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.

The swiss quad the best for me.
Good Morning.
tink you for the Quagi Antenna.

i had a problem for the alimentation of this antenna ! How many distance on hot quad ?
There’s nobody to give me an idea !!!!!!! a real explication
