Portable antenna

Claim 1

A portable RF antenna for mounting on a motor vehicle's side window and enabling easy and rapid mounting and removal, which comprises: an outer RF transfer member comprising a weather-resistant carrier having a first electrically conductive member on its underside for engagement with the outside of the side window; a radiator for location on the outside of the side window and connected to said first electrically conductive member; an inner RF transfer member including a housing and having a second electrically conductive member on its underside for engagement with the inside of the side window; said inner transfer member and said outer transfer member being adapted for alignment so that RF energy is transferred through the side window; means for connecting said outer transfer member with respect to said inner transfer member, said connecting means bridging said inner transfer member and said outer transfer member so as to overlie the side window when the antenna is mounted thereon; said connecting means being located so as not to provide a conductive connection between said first and second electrically conductive members; an electrical antenna wire; means coupling said electrical antenna wire to said second electrically conductive member with the antenna wire being located only on the inside of the side window and not on the outside of the side window.
