Sometimes I can't transmit in specific places (GP338)

[RomeoAlphaJuliet]

So i own a GP338 (VFH) and as a first responder, it goes with me everywhere. The EMS communication system where I live runs on a Repeater so the range is pretty good city wide however sometimes like lets say I'm on campus grounds or in an apartment, I can't seem to transmit on the repeater however i can hear my colleagues talking. As for the apartment, only certain areas in my room am i able to transmit. Could this be due to my antenna? Or something else. (FYI, the radio is stock, nothing has been changed)

You are transmitting 5w and the repeater is transmitting 50w and likely in a far better location, you are going to hear them before they hear you

Is there a way i can solve that or maybe make it better like maybe an antenna upgrade?

Not unless you plan on putting more repeaters up

Or working with your department to get in ambulance relay repeaters to boost inbuilding coverage. It will require working with a vendor/installer and your radio administrator. It also won't be as seamless as it sounds though.

Could you perhaps send a picture of a relay repeater

Pyramid makes some of the most popular ones. They connect to the back of your vehicles mobile radio. You switch to a different channel, and it relays your portable transmission using your high power mobile. Received transmissions from dispatch are received on the mobile radio and relayed at lower power to your portable. I'm not sure if in-band repeating is physically possible in VHF, that you need to discuss with your vendors and administrator.
