Just a simple antenna for 144 MHz portable operating made from indoor TV bunny ears.

No extravant claims are made, but it should perform better than the standard supplied with most handhelds.

Can be converted to a 2el yagi by adding a boom (40cm long) and a second set of bunny ears (both halves wired together), either as a reflector or director.

  • Dipole, inverted V (or V) and ground plane - all in one!

    What length did you tune it to? 19"/each rod?

    Perhaps you can epoxy glue that stud to some 1/2" PVC pipe (actually two pieces of 12" pipe and an elbow), and then stick it out the window - then roll the window up on the pipe to hold it in place.

  • @umajunkcollector 1. yes - 19" is 48cm. 2. Could be OK if your own vehicle (though a roof mounted antenna would be more effective) but modern buses/trains don't have opening windows. And even if they did travel rules prohibit sticking objects out of windows and attracts unwanted attention.

  • If you used that in the UK you would be pulled over by the Traffic police. If you were driving of course.

    However nice idea mate.

  • That's great, Peter, and I like the idea of converting it to a yagi!
