Nope, you just re-invented the quarter wave whip antenna, with your mast
providing the counterpoise... ;-)

Can't tell from the provided picture, but if the elements on the top and
bottom were different sizes, you may have lost more than 3dB at the
frequency ranges the bottom half was tuned for...

Might be interesting to know how well just your mast does... :-)

-D

The elements are the same top and bottom.. actually the very top 7
feet or so of my mast is a wooden rod with the other 20 or so feet
being a standard metal mast.. interesting..

I could use the broken half as a second antenna!!
