What is this inductor looking (RF) component?

This PCB antenna circuitry supposedly is able to transmit on both 406MHz and 121.5 MHz. I can clearly see a micro-strip printed antenna.

Facts: Dual-band 406MHz, 121.5MHz antenna

My Assumptions:
1. 1/4 wave monopole dual-band antenna

Questions:
1. What is that inductor looking thing?
2. How can they transmit 121.5 MHz with such a small antenna?
3. What is the point of the zig-zaged strips? Filter? add length?

FYI
121.5MHz:   Wave length is 8.0988 ft, 1/4 Wave is 2.0247 ft
406MHz:     Wave length is 2.4236 ft, 1/4 Wave is 0.6059 ft

1. I guess the inductor looking thing is actually an inductor
2. is answered also by 3
3. It is (also) an inductor. The inductors probably act as loading coil to adapt the antenna which is to short to be a quarter wavelength for 121.5 MHz.

BTW: 121.5 MHz and 406 MHz are reserved for emergency signals. If you play with that you might get some unexpected visitors.

Yes, this is an EPIRB. Someone will most certainly show up at my doorsteps if I broadcast on those freqs. Thanks –  hassan789 Jan 7 at 16:29
