This compact Glomex Altair TV antenna provides optimum omni-directional performance with both horizontal and vertical polarised signals, thanks to the extended height of the radome enclosure which allows for the inclusion of a vertical element inside. Equipped with a shielded amplifier with low noise factor and automatic gain control (AGC) which ensures a perfect signal both offshore and in the marina. If matched with a V9147 (2-way, optional) splitter, installed between the antenna and the amplifier, it can also receive AM-FM radio frequencies. Universal 12/24V power supply.
