I'm thinking that 14" antenna is problematic for firefighters and EMTs to carry around. While that antenna is designed to give improved performance, especially at amateur radio frequencies on transmit, I suspect that is not the need for the OP's situation. Firefighters tend to carry their radios everywhere, usually on their belts. That 14" antenna is an invitation to damage as previously noted.
I'm thinking that a repair to the antenna mounting to the circuit board is in order, followed replacing that 14" spike with something that is less prone to damage. Perhaps a regular VHF or UHF (depending on which band the OP's system uses) or even a combo antenna that is somewhere around 6" in length would be better suited for this application. Even this may not prevent damage given the general build quality of the Wouxons.
I understand the County wanting to give every firefighter a two-way at the lowest possible cost, but as those of us who have been around public safety for a long time know, the super low cost solution is not always the best bargain.
I issue a Motorola CP200 to all of our EMTs, Medics, and a few of our drivers. Many of them carry their most of the time, and more than a few are also full-time EMTs or Paramedics with high volume ambulance services. We've yet to have an antenna related failure, and very few other issues either.
