subject: building an antenna

On 2019 Jun 14 20:56:00, you wrote to me:

 EV> I used a piece of 300 Ohm Twin Line cable to make a Folded Dipole Antenna

the problem with that is it is flat and you have to rotate it to be
broadside to the station you are wanting to pick up... i'm looking to build
an omnidirectional one so i do not have to rotate the antenna at all...

i think i wrote unidirectional previously but i meant omnidirectional :/

 EV> a bit over 26 Centimeters long for UHF Channel 32 back in the 1960's.

26cm? like 10.25 inches? that seems a little short but it is half-wave...

 EV> Channel 32 uses the Band of Frequencies from 578 Mc. to 584 Mc.

yeah, the UHF band is 470mhz to 890mhz... your freqs there are pretty close
to right in the middle which is 683mhz...
