A new range of terrestrial antennas unique in performance
and design, Fracarro Sigma is perfect for the reception of
Digital Terrestrial television signals.
Patented loop elements and double size corner reflectors
deliver high directivity with an almost total absence of side-
lobes — excellent for reducing reception of reflections.
Sigma antennas feature pre-assembled elements, reflectors
and mast clamp enabling tool free installation. F connector
balun and a unique weatherproof boot are standard. Unique
fibreglass reinforced polymer construction ensures physical
strength and long life.

Active UHF Dipole. Perfect for weak signal areas, adds an
extra 16dB of gain electronically with minimal noise. High
signal level output can be helpful with signal distribution and
reduces the possibility of interference. Protected against
electrostatic discharges, an automatic passive switch ensures
operation continues even when power is not connected.
Impedance match is excellent and power consumption low.
Requires PS12DC or any 12 to 24V DC line supply @26mA.
