FYI: Taking your posted TVFool Report, I determined your Lat/Long by "Bi-Lateration" by matching TVFool "MAP" Results (within 0.1 mile), which allowed me to use Google Map to determine an arbitrary street address in that vicinity, which I could THEN plug into RabbitEars.Info "SEARCH" Engine to derive Current and Post-Re-Pack Results shown below.
I also show the CURRENT Details of WISH/WNDY on Ch9 and (simulcast?) on Ch17, which you see below....the info in third entry for Ch17 is DUPLICATE to first entry for Ch9 [althouth R-E doesn't display any TECHNICAL DATA[. And second entry for WNDY on Ch9 appears to be yet another DUPLICATE, with same Tower Location. There appears to be only one set of 5 Sub-Channels on Ch9, which is duplicated on Ch17.
Although I have Validated TVFool Predictions to be Accurate, they have NOT been keeping up with various Channel Chances. RabbitEars.Info is much better at this, so I have to TRY to merge BOTH Results. First of All, TVFool hasn't even kept up with the CURRENT Channel Changes: Ch32 is actually Ch9 [in Hi-VHF Band], Ch15 is actually Ch29, Ch22 is actually Ch45, Ch23 is actually Ch44, Ch18 is actually Ch34 and Ch40 is actually Ch18. And TVFool did NOT include Calculations for the fol. Stations: WHMB Ch20, WTWU (Ch51), WDNI (Ch19), WCZA (Ch15) and WIIH (Ch8). But you should do your own verification re. what is REAL.
So when channels change (esp. to Hi-VHF Band) the Rabbit-Ears "Signal Margin (dB)" Predictions can be expected to be a bit DIFFERENT than TVFool's NM (dB) Net Margin prediction as different ERP power levels are assigned. Overall, I see that Signal Margin values are perhaps 4-10 dB HIGHER than NM [so average about 7 dB]. And then there are the exceptions: WFYI (Ch21) has NM=26.9 dB, but SigMargin = +39.99 dB; WQDE (Ch33) has NM=6.5, but SigMargin = -39.89 dB; and WUDM (Ch39) has NM=-5.9 dB, but SigMargin = -39.98 dB. Perhaps someone else can reconcile these BIG differences.....
As you have surmised, CURRENTLY you only need Hi-VHF Band Reception for STRONG WHMB (Religious) on Ch7 [if that is of interest to you]. Since WISH is CURRENTLY being broadcast on both Ch17 and Ch9, you would not "NEED" to receive "THE CW, etc" on Ch9, except perhaps as a backup mode. So depending on whether you want Ch7, there may NOT be a CURRENT "NEED" for a Hi-VHF Antenna capability. [And weak WIIH on Ch8 is another Duplicate for "THE CW, etc" and might be too weak to receive anyway, esp. with Strong Ch7 Adjacent Interference....and BTW TVFool did NOT include it in their list.] Also bear in mind that even UHF-Only Antennas can receive STRONG Hi-VHF Stations....although "typically" they MIGHT have lower Gain Forward than to the Rear (YMMV)....I have included Hi-VHF Azimuthal Plots for many of the UHF-Only Antennas I have analyzed (with Loss through likely UHF-Only Balun NOT included).
IF you don't care about Religious Programming (so don't "need" reception from Due-North), "Best" reception results for long term reliability "should" be provided by pointing Antenna (with Reflector) towards Indy at about 227-deg (re True North). Extremely STRONG WIPB (Ch19) "should" come in from 127-deg, but may require rotating Antenna a bit more in that direction so the Narrow Beamwidth SIDE NULL of the Antenna doesn't fall exactly in that direction....which MIGHT be more towards 210-deg (more or less). And if you DO care about reception from Due-North, you MIGHT succeed by removing the Reflector (as you have done)....but at the risk of lower reliability on your weaker UHF stations. Good Luck....
Post Re-Pack, 11 channels CHANGE [out of 24 on the list], including WHMB (Ch20, Religious) to Ch7 in Hi-VHF Band and WUDZ (Ch28) to Ch6 in Lo-VHF Band...so you should check your program listings to see if you even WANT Ch6....which would be fairly weak and likely would need the Monster Winegard HD-8200 on a Rotator to receive....or one of my DIY Lo-VHF Antenna Designs. In glancing at the Post-RePack List, I see that R-E's Calculated Signal Margin for WISH (Ch26, "THE CW" etc) greatly improves, while the Ch9 Simulcast is much weaker. So again you might NOT "NEED" anything other than a UHF-ONLY Antenna.
CHANNEL CHANGES:23 to 19, 45 to 22, 29 to 15, 20 to 7, 44 to 23, 46 to 17, 51 to 28, 17 to 26, 19 to 16, 28 to 6, and 47 to 36.
