NORTHWEST ROCHESTER, MN FINAL SETUP
Winegard 7694P Antenna pointed straight south in Attic
Winegard LNA-200 Pre-amplifier
Antennas Direct CDA8 Distribution Amplifier (Optional, for long runs)
: Good signal on KIMT (3-1 CBS), KAAL (6-1 ABC), KTTC (10-1 NBC, 10-2 CW), KSMQ (15-1 Austin PBS), KXLT (47-1 FOX), and K25NK (58-1 3ABN), Moderate signal on KYIN (24-1 Iowa PBS)
I'm not concerned with any stations weaker than KIMT, so the target stations are all within a 21 degree window to my south. I don't really care if I lose access to K25NK either.
I'm working on trying to get better/more reliable signal in my area. I've tried a few cheap antennas and got nothing aside from K25NK. I got the Amazon Basics version of a Mohu Leaf Ultimate and it's passable.
However the signal is weak and flaky. I get artifacts on occasion at it's best, but at it's worst, I lose KTTC altogether and sometimes KXLT is bad, but not completely gone. Interestingly, KIMT and KAAL have no issues. I'm mounting the Leaf on a south facing wall about 20' over ground level.
When I plug it into my computer with a Hauppauge 950q and use their Signal Meter, I get about 22db SNR on KTTC and KXLT in good conditions and 24-26db on the rest. I had run things through a -7db splitter before but started losing signal with just one more split, so I got a CDA8 drop amp and that problem went away. I haven't seen any noticeable drop in SNR through that amp.
I was thinking about going to a 4228HD. That antenna is likely total overkill on UHF but I'm concerned it might not be enough in VHF-HI to receive KTTC. I'm not opposed to mounting in my attic, which is what I'm planning on doing with the 4228HD.
I'm also not sure if I'm going to need a pre-amp. I'll likely need 35' of cable to reach the drop amp but I may have to go 50' since that's the next step up from 25 and I don't have a crimping tool / know how to properly crimp a coax cable.
