Sepura portable antennas are
colour coded by the frequency band they cover ONLY for the handset they
are supposed to be mated to. Once an antenna is separated from a handset, there is no way to tell what it is!
For example: A Yellow dot antenna for an SRP/H series covers 440 - 473MHz A Yellow dot antenna for an STP series covers 407 - 473MHz
The
bit of the antenna that you can see is only HALF. The other "half" is
the groundplane of the radio board, and bit of capacitive coupling to
your body. For this reason, you shouldn't really mix and match antennas
across radio models.
