  • Patent number: 5528251
    Abstract: A double dipole tuned antenna is presented having the capability to enhance the television reception, particularly on VHF frequencies. The antenna has an outer, longer diverging dipole antenna connected near its midsection to an inner, shorter, parallel diverging dipole. Also connected to the inner dipole is a large helical coil and a smaller helical coil. A capacitor is placed in parallel across opposite ends of the smaller helical coil in order to tune the device. The device is particularly useful for tuning VHF frequencies although it is also useful in tuning UHF frequencies.
