coatenna dipole scanner antenna

Complete details for building a cheap simple half wave dipole antenna for scanning. Can also be cut for lengths useful for broadcast HDTV [and it works rather well]. However, element lengths can get pretty long at frequencies below 100Mhz. Since I'm not a DXer this works out well for me. And just to be clear, do NOT attempt to transmit through this rig.

@littletoy01 Plain old RG-6.

Thanks for the info.

I was wondering if you can tell me how long my cooper would have to be for freq. 135.500

Thanks for your time .

I built the same antenna as you have but I was wondering what would be the freq. of 18 inches each copper wire

Thanks

thanks man. good vid :D

that would work for a tv antenna as well if you cut them for that, cool i like it

Nice! I will have to try that. I just ordered some connectors so I can start experimenting with home built antennas. I got an N connector to make a quarter wavelength antenna. I also got a N male to F female adapter and a F female to BNC male adapter so I can use standard 75 ohm TV coaxial cable.
