Do you have your radios (or antenna mast) grounded?
-Donald Yes the mast is grounded... I guess I thought with a dipole it would be worthless without it's bottom half, or at least seriously compromised. |

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 -- "A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort." -Herm Albright |

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