This is an interesting quagi antenna plan.
Total Boom Lenght is 3 m.
Original design By Roberto Turco
If you are inderested on homebrewing your own antenna, find more QUAGI antenna plans here.
DL9KCE released a new version of his ICNIRPcalc software that allows you to calculate safety distances for many know amateur radio antennas with respect to ICNIRP limits.
Calculations are done by considering many depending factors, like …
ARI Milano obrained last october, for temporary period , the permission to operate on the 500 KHz band to develop experiments.
After having obtained such permission, ARI Milano home made a vertical antenna with a capacitive …
Last week I’ve received the Baofeng UV-200, the Chinese handheld dual band transceiver under 50 USD.
I’ve ordered the radio at 409shop.hk web site, and have choosen the registered letter Hong Kong post method to save …

I was uploading the latest LoTW entries to ARRL LoTW today, and the TQSL application found errors on validating some QSOs done in Contestia mode.
Looks like the Contestia mode is not recognized by ARRL …
DEAR HAM FRIEND,
I MAKE SAME ANTENNA AND I HAVING VERY GOOD RESULTS!
HAVE NICE DAY AND MANY THANKS!
MIKE 73 DE Z32MA
50.115 EVERY DAY AFTER 16:00 LOC TIME
Hy Roberto,
Y try to make thus Antenna……….Looks very good !
73 9A7PJT
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.
