As mentioned in a previous threat, I have an old chimney mounted UHF/VHF antenna. Since the digital switch, it's not quite doing it's job. Some signals are just at the threshold where they break up. One suggestion was to take the old antenna and clean up the connections, replace the cable, etc. It's been too cold and wet (yes even snowy) to get up on the roof, so I've had some time to think.
I have an old smaller combo antenna. Could I use pieces from it to extend the UHF section of my current antenna? Is there a formula for the length and spacing that this would mess up? Just a thought.
