I remember seeing in TV Guide and other magazines and papers ads for a plug in TV antenna. "Use your house's electrical wiring as a TV antenna" it would say. It was a small plastic cylindar with a power plug on one end, and twin lead also running out of it. Don't know what was inside, heard there was nothing inside, not even a coupling cap to the powerline. I don't think you'd want to use the powerline as an antenna anyway, there sometimes be noise from sparky furnace motors and such to put spots in TV pictures.

I dont know if they were sold in the USA , but here in Canada in the late 1980s there were these fake satalite dish with rabbit ears things sold for $19.95 they were made in China and were really cheap and they had this tuning control that , when turned switched off one of the antenna leads , leading people to believe that it was a fine tuning control when both connections were switched on it . The dish had dipole sticking out in front of it , it was for UHF . These units were on the borderline of false advertising and did not recieve any better than the original singal antenna in most portables . |

antenna's
Right now im running a really ratty old channelmaster circa 1965? Still have to restore it . It's not as clear as it used to be . But I would like to experiment with different antenna designs , the Telesine on steve's website would be a fun project . Does anyone know if the outer rings were for VHF and the inner one's were for UHF , or was one of these directors or reflectors and the small ones were elements . one thing with the Telesine , it would require a great deal of materials to build .
kx250rider that would be great if you could get some pics of those antennas especially a stack . I have never seen these types of antennas , only in books or on the net . TV didnt show up here till 1956 and the climate and damp weather has long since destroyed these . My channelmaster would be considered old . If you could zoom in on the insulators and other connections that would be really appreciated . |
