The YB806-82 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.

The feed element of each antenna is of full folded dipole construction, welded to the mounting boom for maximum bandwidth, low intermodulation performance and reliability. The passive elements are through mounted to the circular boom section and welded at each side before plating. The alodine protective finish provides a conductive surface to ensure effective earthing of the antenna when mounting.

The YB800 Series are offered in 3, 6, 9, 15 or 20 element form and are generally held in stock for immediate delivery in the commercial bands.

YB800 Series antennas 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 section in the back of this catalogue.

YB800 Series rest at ground potential and provide excellent lightning protection and reduced precipitation static noise. Termination is via an N Female RF 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.
