Default Decided to press back into service

I had my roof replaced last year - - and decided to not go back with the CM-4251.

I pressed the old CM-4251 back into service for the back bedroom - sorry.

21 channels from DC - mounted only 6 feet off the ground.

Default Nope - - - I modified it

I tested at least 3 different configuration on the 4251.

I built a replacement using cooper which should have worked better but did not because I used a wood bracket. If I could have used plastic bracket - - I think it would have worked better.

Although I did not model it - - (mainly because I could not figure out how) - - but I made the triangular parts just slightly larger - - and I also made the reflector larger using parts off an older VHF antenna.

WOW - - I found the photo on the digitalhome forum from 2012 when I did this. (see attached and link below)
