The antenna is inexpensive, comes in all varieties you could need, and the semi rigid wire is perfectly stiff. I have abused these antennas while flying 50+ mph into dirt, concrete, trees, and various other objects woth great success. The lobes and wire have even been caught in my props woth only supeeficial damage. I get rhcp in red, and lhcp in green so i can easily tell them apart at a glance. Signal strength has been great everywhere I want to fly. I use them as both rx and tx. They are cheap enoigh to buy several, although I am! Still on my first set after 2 momths of every day hardcore flying.
