Chicago south suburbs, according to antennaweb 25 miles to xmitters downtown..
Comcast + rooftop OTA through TIVOs. OTA is cleaner than Comcast HD locals (mpeg compression), plus OTA works those couple times a year after a big storm takes down cable for days as happened recently.
Anyways: had been using a winegard 4400 UHF that works well, but does nothing for WBBM (CBS 2, RF-12 VHF 8kw). Found in the attic an old RS 15-1702 (small V-U-FM) still in the box. Puzzling where it came from, previous homeowner for sure...bought but never installed.
There's nothing in VHF-low band in Chicago I'm interested in, just CBS @ VHF 12. Took measurements of the 8 VHF log elements on the ant, appears to work half wave in VHF-L band, full wave on VHF-H. Simply chopping the long elements to retune to full wave RF 11-13 should work? Chopping to half wave would likely pick up too much UHF/interfere with the Yagi on the front of the antenna. Elements would be chopped to 26",27",27",28". Any reason this would not work?
Spacing of the elements in question is 11.25" (4 crossconnected dipole halves or 8 elements)
