Hello world or maybe just Locals!

My first VHF/UHF Dual Band Antenna.

Made from aluminum rods and L-bracket. Attached to 8′ aluminum pipe.

Dimension and drawings is available on:

Measurement was done with Surecome SW-102, thanks to my friends KC2IGS and  KD2EKZ. Thank you guys.

As you could see from the chart there is a very high  SWR on 220 MHz band, so I will install a similar design antenna for those frequencies.
