The YBS806-82 antennas exhibit narrow beamwidths and high front to back ratios to help minimise any potential interference to and from other systems. This particular model covers 850 to 930 MHz, providing 11 dBi gain across both 868 and 902 to 928 MHz ISM bands.

YBS806-82 is manufactured from all welded 316 grade stainless steel these antennas provide identical performance to the YB800 series yagis but are better suited for extreme climatic or corrosive applications. The feed element of each antenna is of full folded dipole construction, welded to the boom for maximum bandwidth and reliability.

The YBS800 series antennas are offered in 3, 6, 9 or 15 element form and are available ex stock in small quantities. They can be configured in stacks or bays for higher gain applications in either horizontally or vertically polarised systems. Application details on phasing and mounting yagi antennas are included in the technical notes at the back of this catalogue.

Yagi antennas rest at ground potential and provide excellent lightning protection and reduced precipitation static noise. Termination is via an N female connector fitted to a short 9302 Durathene cable tail. Durathene is a PTFE dielectric and polyethylene jacketed cable providing superior resistance to weathering and abrasion and is less susceptible to bird attack than standard PVC sheathed cables.

Ideal for ISM band IoT technologies such as LoRa and Sigfox.
