The Extragain range of aerials is built without compromiseSignal distribution is 39clean39 because the directors are constructed from four straight half wave elements mounted at the optimum spacing and angleMaximum signal transfer from aerial to cable is guaranteed with tuned baluns and resonators whilst the full wave reflector shields the dipole from unwanted 39ghost39 signalsEvery component works with the next to make the most of every microvolt of signal available, which is why professionals choose the Extragain for larger TV systems and problem areasSuitable for FreeviewHigh forward gain for increased signal level in fringe reception areasMatching Balun for impulse noise reduction and Improved Anti Ghosting with reduced multipath corruptionForward Gain 14.9 dBiFrontBack ratio 26dB16 degrees acceptance angleWindage N at 130kph 80Length 1455mmWidth 546mm
