UHF Low Profile Transit Antenna, 450–470MHz
The RFI TLA400-70 is a heavy-duty, low-profile UHF antenna built for buses, coaches, trains, and commercial fleets. Cable and connector are sold separately, this listing is antenna only.
Overview
The RFI TLA400-70 is a low-profile UHF transit antenna covering 450–470MHz, engineered for permanent roof mounting on buses, coaches, rail vehicles, and commercial fleets where a traditional whip antenna is impractical due to height restrictions or vandalism risk.
Its rugged cast aluminium construction with a baked enamel finish keeps a clean, factory-style appearance while standing up to daily fleet use. The antenna is supplied pre-tuned and ready to fit, using a 44mm mounting hole spacing.
The antenna ships with an N connector but no cable or matching connector. You'll need to sort a cable run and N-type connector to suit your install, talk to us and we'll help you pick the right length and cable type for your vehicle.
Key Features
- Full 450–470MHz coverage, supplied pre-tuned means no field tuning required, for installers fitting out vehicles on a schedule.
- Low-profile transit design means reduced risk of impact damage and vandalism compared with a traditional whip, for fleet vehicles operating in depots, car parks, and low-clearance areas.
- 44mm hole spacing, screw and gasket mounting means a straightforward permanent roof install using the standard transit mounting pattern.
- Rugged cast aluminium with baked enamel finish means a clean, factory-style appearance that also stands up to weather and daily fleet use.
- Omnidirectional radiation pattern means consistent communication while the vehicle is moving, in any direction of travel.
- Rated to 100W input power means it handles serious mobile radio transmit power without drama.

- Public buses and passenger coaches
- Rail vehicles
- Emergency response vehicles
