G'day,
| I want to construct a rotating dipole for 24Mhz and 18Mhz with a single
feed
| line.
| Does any one have any construction details, experience, ideas....
| It could be made using traps or separate elements on a very short boom.
| The one feedline and rotating capbility are the main requirements
Sounds like a good case for an open sleeve arrangement like the Force 12
driven element cluster. I believe the necessary details are in the ARRL
Antenna Book.
Failing that I guess some sort of matching network at the feed point,
maybe relay switched or there is possibly some combination of element
length and L or C that will auto-magically work on both bands.
Regards,
Mike VP8NO
