Hi everyone,
I haven't posted here in a while, been following/reading the thread on and off though.
When the 53x models came out, there were some discussions about the tuner being higher quality, and wondering if anyone who has both versions (pre 53x and post 53x) to compare.
Anyway, some of you may remember the OTA issues I've been having locally with some channels. Well... I just made new findings, by "mistake".
Had some free time Today, and as I unplugged and replugged wires over and over, attempting different configurations, at some point the "faulty" channel came up! And quite well too! The signal was strong enough, around 36 on the Maggy when 15 is enough to get a solid lock. I scratched my head, wondering how in the World I could go from 0 to solid signal without any apparent change in my wire setup. I checked the other channels, and found that although there wasn't a significant change in signal for local broadcasts, both CBS and NBC came in weaker, yet still over 50% so more than enough for a lock. I thought I magically scored the dreaded FOX channel, but then I got to PBS, which went to 0. So it appeared I lucked out on getting one channel (FOX) but lost out on another one. Even more head scratching...
I went back to take a look at the wires, and immediately figured out that I plugged the antenna input in the "OUT" connector on the Maggy.

I could not believe it. It appears that the internal splitter in the Maggy passes the signal through in both directions. And, somehow, it filters the signal differently depending on whether you plug your source in the IN or OUT connector.
So, when I plug in the IN, I get a stronger signal on most channels : UHF 14 (NBC), 22 (CBS), and 43 (FOX) but it somehow filters out 32 (PBS).
When I plug it in OUT instead, then I get channels 32 (PBS) although weak but enough for good reception, but I don't get channel 43 at all and 14 + 22 are weaker although still lock in with no pixelization . That's expected since I'm actually passing the signal through in the wrong direction, but why does that one channel 32 come in in the "reverse" direction but not in the "right" direction, and vice-versa for channel 43? My head will soon bleed from the violent head scratching : help!
When I leave it in the IN, and then link to my TV from the OUT (as it should) I then get all the channels in my TV's tuner, including 32 and 43. But, that's not so "new" since my TV has always outperformed the Maggy's tuner. I even get extra channels on my TV that I never even got a hint of getting on the Mag. Plugging the antenna in the OUT, and wiring my TV from the IN, yields similar results as in the Mag : PBS on channel 32 comes in (but much weaker than when "properly" wired but FOX on channel 43 is a no-go. Other channels, such as 14 and 22, get in, but weaker.
Has anyone EVER seen something like it? Does anyone care to test their own local OTA setup to see if they get similar results if they reverse the IN and OUT? Especially if your local channels are on similar UHF bands? BTW, for easier understanding, all the channel numbers I listed are the "real channels" not the "DTV or PSIP data" channels.
I hope my post isn't too confusing. I have a hard time figuring this thing out. The bottom line is:
- When antenna is plugged in the "IN" as it should, most channels (including 43) come in stronger, but I don't get channel 32 (but I do get it in the TV's tuner).
- When antenna is in the "OUT" connector, and the TV in the "IN", in the reverse order, then most channels are weaker, but still enough for safe watching, I lose 43 altogether, but I gain 32, weak but watchable.
Of course, this is puzzling, but still doesn't solve my original issue, since I record many shows on PBS that I can't get anywhere else, other than pbs.org. So, it looks like I'm actually better off leaving it plugged in the "OUT" connector, so I at least get PBS, but I won't get FOX this way. Most FOX shows are broadcast on local channels too (Global TV and CTV) so I rarely need to record FOX, I mostly watch it live for sporting events and such. There's always the option to reverse the connexions if I ever need to record FOX.
