The Quanum Pagoda-2 omnidirectional antenna was designed by Maarten Baert who wanted some key features to be incorporated into his design, these were as follows;
• Good omnidirectional radiation pattern
• Good axial ratio
• Compact dimensions
• Easy to manufacture and at low cost
He succeeded in his goal in designing an antenna with these attrubutes. The Quanum Pagoda-2 antenna is built using regular PCB's spaced at exact intervals with the final design taking months of fine tuning. The Quanum Pagoda-2 also have spacers in between the plates to ensure they are kept aligned with each other. The end result is an antenna with a smoother radiation pattern and a significantly better axial ratio than most other antenna's.

Give good FPV range and work well behind trees and other obstructions.
The shaft between SMA connector and the active elements is bendable but I'd still be careful not to bend it too sharply - like any antenna.Good signal and durable
