The antenna is one band antenna. It works on TX when it is tuned to serial resonance. The antenna works only to RX when this one is tuned to bridge resonance.

The antenna has efficiency like a lambda/4 vertical antenna. As I believe in the antenna the outer braid of the coaxial cable is radiated. It is need a part of the coaxial cable near antenna to place in vertical position.
