With most of the Heavy Duty (and Dual Zone) controllers we offer an optional Extended Antenna kit. This kit includes two antennas; a 1.5" "stubby" antenna and a 5" magnetically mounted antenna with 16' extension cable. This extension kit will in most cases, quadruple the range of our wireless remote controllers. In addition, if you're installing the LED controller in an area that is encased in metal (which makes it difficult for the RF signal to communicate), using this extension antenna kit will in most cases resolve any reception issues. The 16' extension cable gives you flexibility to mount the 5" whip antenna in the best location. Note that this extended antenna kit improves the reception of the RF wireless remote controls. It does not in any way improve Bluetooth reception.
