Optimized antennas for compact radios

07.01.2025 by Ari Alonen

CAQ sleeve fed quarter wave whip antenna can be factory-optimized even for compact radios used in GNSS, IoT, PMR, LTE, LoRa, Remote reading, RTK, Telemetry, and similar applications. Its adjustable sleeve feed enables precise tuning on ground planes of varying size and shape, ensuring an optimal radiation pattern, gain, and impedance match. An optimized quarter wave whip antenna clearly outperforms other small-size, like helix and PCB antennas. Contact us to customize a CAQ antenna perfectly suited to your radio enclosure or PCB.

LP lightning protectors are maintenance free enabling continuous communication without need for service or replacement. This makes the difference compared to fuse like operating lightning protectors.

Female to male connector interface enables easy insertion also to already existing installations.

LP has a M8 cable lug for low impedance grounding.

Center and outer conductor are DC shorted and on the same ground potential.

Quarter wave construction makes LP to behave as a band pass filter reducing noise level and cancelling even harmonic frequencies.
