Some of the major commercial brands for both base and mobile are Pulse/Larsen, Andrew, Sinclair, Telewave, Laird/ Antenex, Maxrad/PCTEL, Commscope, RFS/ Celwave, Comtelco, Sti-Co, Kathrein, Commander Technologies and a few more. Some have been bought and sold recently and its hard to keep up with who owns who.
In the old days it was Phelps Dodge, Antenna Specialists, DB Products, Larsen and some others and they are sort of still around but under different names.
You should not find any Tram or Comet or Diamond antennas in a professional/commercial installation.
