ABSTRACT:
The invention pertains to an extendable directionally adjusted dipole antenna particularly suitable for use with recreational vehicles. The antenna includes a vertical column having an extendable dipole arrangement at its upper end utilizing flexible actuators associated with a pair of reels whereby the actuators and associated telescoping antenna assemblies are simultaneously extended and retracted. An operating shaft for rotating the reels extends through the column and either manual or electric means rotate the shaft. The column is rotatable for directional adjustment, and under manual control the shaft extends through the vehicle roof permitting interior adjustments.
