Most of the vehicles currently manufactured in the world with a KES (keyless entry system) use a number of short antennas. Depending on the quality of the vehicle and the system they use 3, 4, 5 antennas (in the door handles, interior antenna, in the trunk handle…
Rooming an antenna in the car sometime becomes a very hard task.
This kind of antennas keep the performance saving space, little bit wider, but very reduced length in the total space.
|Depending on the requirements and location of the antennas in the vehicle and taking into account its exposure to environmental conditions, grade IP waterproof, mechanical robustness, etc.. PREMO offers from LPM technology, to Polyurethane, mixed LPM-resin and HPM.|
New Diabolo with Low Pressure Technology (LPM)
New Diabolo with PU-resin
The main technical and economic advantages:
Antenna is measured in resonant mode.
The specification chart is a reference guide for the most common required values at working frequencies of 125 kHz, 20 kHz and 134.2 kHz. Any other inductancevalue at LF or tighter tolerances can be provided. Please contact our sales department for any inquiry.
