Hello everyone,
I'm new to RadioReference. I tried searching for previous chats about my issue, but I couldn't find anything that caught my eye, so here I go making a new thread.
I have a Motorola XTL2500 380-470 MHZ UHF installed in my Fire Department POV (Chevy Tahoe). It is hooked up to a Laird Phantom 450-512 MHZ UHF antenna. The antenna is hidden behind the plastic cover of the D-Pillar on the Tahoe, to avoid drilling holes in the roof.
Our primary channels run from 451-465 MHZ. I can receive calls from Dispatch fine. When I try to transmit to Dispatch, they can barely understand me through the static. When I transmit on my department issued 5W Kenwood handheld within territory, they receive my message clearly. The Motorola is a 45W radio....so it should be just fine!
I have the code I pulled from the plug, but I do not want to post it publicly. Can anyone offer any ideas as to why I might be getting such poor transmission performance out of the radio? Perhaps mismatched antenna/radio ranges? Could being mounted behind a plastic beam really kill my signal so much that I can't call dispatch from within our territory?
