The MedFER "NC" beacon antenna is a 9 foot section of 2 inch ID aluminum conduit. The top hat is an old UHF TV parabolic reflector grid that is covered with window screen. The window screen probably wasn't necessary but this once TV antenna was modified for a microwave antenna by adding the window screen. Now in it's third life it serves as a top hat. The conduit is supported by a section of fiberglass which once was the shell of a commercial VHF "Stationmaster" type antenna.
This view shows the loading coil with the cover lifted. The coil base is made of 1/4 inch Plexiglas. Holes were drilled into the base to support the 1/4 inch diameter fiberglass rods that form the basket weave form. The rods were cut from old bicycle flags. The coil is wound with 18 gauge silver plated Teflon insulated wire. A copper ground strap connected to the metal building provides a good ground for the transmitter feed point. The transmitter final amplifier, a BS170 FET, is located under the building roof. The present exciter is an oven controlled signal generator capable of 0.1 Hz frequency increments.
