RHA68 base-station antenna 66-108 MHz 4-element 2.14 dBi 50 Ω UHF-female
Sirio
This 1/4-wave antenna is designed for base station use in the 66–108 MHz frequency range. It can be tuned to the desired operating frequency using the supplied tuning chart, making it a flexible solution for a wide range of VHF applications.
The durable construction consists of corrosion-resistant aluminium and a sturdy die-cast base for safe and easy installation. Its omnidirectional radiation pattern provides even coverage in every direction, while vertical polarisation is ideal for base station and radio communication use.
The antenna provides good efficiency, a low VSWR and power handling of up to 500 W, making it a reliable choice for professional applications.
