For remote antenna setups to compensate for associated cable losses.
Please note: when using low loss setups the high gain of this antenna may lead to an overload of our dongle RF input stage. In this case the RF gain of the dongle has to be reduced. Very short cables may lead to deterioration of reception quality.

Also includes:

• Bias Tee for power supply of the LNA over USB-jack of a Computer; USB cable
• Aluminium mast clamp (no mast)
