A dual LNB/TV antenna multi-switch allowing DC voltage provided by a satellite receiver to travel through the terrestrial antenna input without causing interference, distortion or lowering the signal strength of the satellite and terrestrial antenna pictures. By including an external DC block adapter with the invention, the multi-switch can be used with both amplified and non-amplified antennas and not require an external power injector.

Dual LNB/antenna multi-switch with DC path for the terrestrial television antenna port

A collapsible antenna is provided; it is preferably a folded dipole antenna. The antenna has a main body section and two arm sections attached to the main body. At least one of the arms may be moved from an extended position to a collapsed position, thereby reducing the overall length of the antenna. Preferably, the arms may be rotated or pivoted from a first expanded configuration in which they extend in opposite directions from one another to a second collapsed configuration in which they subtend an angle substantially less than 180&deg;. Preferably, the arms extend from the body section in substantially the same direction when they are in the collapsed configuration. A locking mechanism selectively secures the arms in both configurations. Alternatively, one or both arms may telescope. The invention also includes mutual inductance cancelling coils for further reducing the overall length of the antenna without reducing the effective length of the antenna.
