A DTV antenna
This seems to be the only news group devoted to the topic of antennas.
(and the origins of the universe). So maybe you guys can help me with this. I have been experimenting with fabricating a decent indoor DTV antenna. I have tried several things. What I have now is two bowties spaced about 7 inches apart on a wood dowel. A peanut butter jar with rocks in it makes up the base. It seems to give pretty good performance. It could be better. But I am wondering about a few things. 1) Right now all the digital transmissions are in the UHF band. but in 6 weeks, three stations will move back to their VHF assignments in the VHF high band. How well can I expect my antenna to work in that frequency band? 2) I have not trimmed or dressed the twin lead from the bowties. I understand that twin-lead can act as antennas. So what is the best way to manage the twinlead? Cut it back? I noticed that when i laid the leads together, in an attempt to make a neat assembly, I got signal cancelation. 3) Any suggestions to improve this design? 4) Any suggestions for alternitive DIY designs?
