Question: Replace existing antennas, or relocate one of my antennas?

Want to give everyone an update on what I did recently. I decided to replace my Winegard HD9032 antennas with an Antennas Direct DB8, along with replacing the cables, & saw a major difference on the UHF. I moved the VHF antenna (Antennacraft CS600) back to the very top of the pole, while mounting the DB8 just below that. Not only are my full power stations coming in with no trouble (always had problems with stations in the channel 40 - 48 range), but 3 low power stations are coming back in. WCPX (ION) on RF 43 always came in & out at night, & WLS-TV wasn't affected as much with my old combo antenna on RF 44, but would always go in and out on the Winegard, & from time to time, WTTW on RF 47 was even affected. With the DB8, no problems with RF 43, 44 or 47 (don't care for WSNS on RF 45, as I don't speak Spanish). WWME-LD on RF 39 in coming back in with no problems (was coming in on the Winegard when it was dry, but was out completely on rainy days), & I'm getting W25DW-D on RF 25 (my mom's happy that she can watch HSN again :( ), & getting WESV-LD on RF 40 again (don't watch since it's Spanish). While I don't care, but while WCHU-LD has a signal over Gary, IN, it still doesn't come in, primarily due to interference from WEDE-CA on RF 34 (they're still in analog), & maybe from WMEU-CD on RF 32. Since moving the VHF antenna back to the very top of the pole, I get WOCK-CD again. I'm still using the same pre-amp (RCA TVPRAMP1R VHF/UHF pre-amp), & the same coupler (Winegard CC7870). While I currently have the Winegard HD-1080 antenna down, that antenna will eventually be put back up, since I'm starting to have problems with WYIN again, since removing the antenna, in order to remove my Winegard HD9032 off the pole completely, move the Antennacraft antenna back to the top of the pole, & place the DB8 underneath the VHF antenna.

While I didn't exactly get the answers I had hoped for, replacing my UHF yagi antenna for a DB8, & replacing the cables made a major difference. Replacing the cables alone would not have improved the reception on certain channels. From now on, I'll stick with 4 & 8 bay antennas for UHF (2 bay if I ever move to Milwaukee, as I would live in the Milwaukee city limits, once I can afford to move), & as long as Antennacraft continues to make a VHF only antenna that's optimized for 2-13 (like the Antennacraft CS600), I'll get that too.

Your setup has a lot of wind-load. Do you have it secured with guy wires?

Believe it or not, it doesn't sway as hard with the DB8 on the pole like it did with the Winegard yagi did (there were a few windy days between Christmas Eve & today). I have the pole 20 feet off the ground, with the VHF antenna at the very top. From the top peak, it's about 10 - 12 feet above to rooftop. I can't go any higher, due to my home being a trailer, or it would be up higher, & I would also have 2 separate poles (one pole dedicated for antenna for Chicago & Cedar Lake, IN, where WYIN transmits from, & another pole for just South Bend, IN full power stations). I don't have guy wires, & not sure where I could even mount them, since the yard behind me isn't mine, & the next door neighbor won't let me tie down the pole thru their yard.

Wind sway/oscillation will cause havok with any dtv setup... The tiny beamwidth on your 8bay would make that effect even worse. Unless you literally have no yard even some guying or other methodvof stabilisation would help a little...

I'll wait & see. So far, my new setup has handled wind better than the yagis I used to use. On the windiest days with the yagis, the pole swung left & right rather heavily. So far with the DB8 up there, it hasn't done that, or very little. Using the small VHF only antenna has also helped keep wind resistence to a minimum. I'm just happy that everything is coming back in again, & especially glad that WWME-LD is back in, so I can watch Bounce on 23.2 (if it was just MeTV, which is on 23.1, I can get that on WCIU 26.3 if necessary). Though I'm white, there are some movies I watch on Bounce.

I dont mean mechanical problems... Those oscillations cause a big drop in signal quality.... Of course if quality is holding up on all stations in all weather then may not be a big issue

As long as the signal strength remains above the digital cliff, wind sway should have no perceptible effect on your picture.

If the sway causes the antenna to move in and out of a null, it will cause signal drop outs and pixellation.

At the frequencies of TV reception antenna movement is irrelevant as long as the signal is there.

I can assure you sway makes a big difference at tv frequencies... Null or otherwise... reducing sway will give you a longer system life as you wont drop below the digital cliff until other components have degraded much further than what would otherwise be required....
