Just curious does anyone have signal quality inconsistency through out the day and or over the course of several days?
My setup is
Tablo tv 4 tuner
Antenna in attic. It’s a clear stream 4v
Line from antenna to Tablo is direct.
There is one splitter on the end to provide line to tv and one to Tablo. This didn’t see to change quality when removed.
Just sees if I scan stations sometimes it’s 5 free and sometimes are 3 orange. One station is over hundred bars and sometimes is 5 green and sometimes it’s 1 red. Not sure it changes so much.
I know attic isn’t optimal but I didn’t want to go mast outside as I already patched holes previous owner had from direct to not to mention with an HOA I knOw they can’t say. I bit no one else has one so don’t wanna be outcast lol.
I got an amazon basics flat style 17 dollar antenna to have live tv in bedroom and that has more consistency than my 100$+ amplified antenna and I refuse to accept it lol.
It’s weird Bc even when a station has 5 green on the signal via Tablo sometimes you get a few seconds pixelation to where picture is scrambled and audio is jacked and then the back. I know with air things can interfere but just odd. Just trying to figure out where the issue is.
My cord cutting has been nice but it is just mildly annoying to have those random issues with my better antenna and DVR but not with my crappy poorly hung and hidden cheap antenna.
The other day the World Series went from clear to frozen and unwatchable to watchable. It was almost out for 2 min.
Antennas placed in attics have to be located in a “sweet spot” where all the signals converge. Typically that is one spot in an attic. Not every attic location is suitable for antenna placement. The C4 is a great antenna - have several friends who use it in their attics. Sometimes one has to search for that “sweet spot” experimentally. Otherwise the antenna can suffer from signal bouncing and overlap which results in a combination of strong and weak signals on the same frequency (the “up and down” effect). The C4 is actually one of the best attic antennas.
The larger the antenna, the less sweep it has for pointing at the broadcast towers. The C4 typically has a 60 degree sweep. Are all your stations within that range?
Is the C4 looking through any trees in the attic? Trees can cause a signal to fluctuate on windy (or even breezy) days.
Aluminum ducts and pipes in an attic can cause crazy signal reflections.
Does your roof have an metallic particles in the tiles? Those can attenuate a signal. Your smaller antenna can be pointing through wood (walls) whereas the C4 can be pointing through a different material (roof tiles).
I’ll have that same issue from time to time where I’ll have the perfect 5 green signal and I’ll have the pixelation with an audio skip, or sometimes no pixelation but there’s an audio skip or dropout. It can be mildly annoying especially when I have a "perfect " signal
Unfortunately the couple for me that change randomly within a 30 min show is NBC and Fox, abc does it sometimes but only on the further away station (I get two ABC ). Fox is worse for me but that one is a 13.1 and NBC is 8.1 for channel frequency.
I got this for the bedroom and literally laying it flat on the armoire beneath the TV it gets all channels my Clear channel 4v
The Clearstream 4 will get you all the channels pointed at 30 degrees (in the green block of channels) without the preamp but none of the others. The preamp may be overloading however an RCA TVPRAMP1Z (is that what you have?) should not. The green block signals at 30 degrees LOS should not require a preamp.
The Amazon Basic being multidirectional will get those channels at 160 degrees that the Clearstream will not. The 130 degree spread between the channels is outside the Clearstream’s spread and beamwidth even if pointing between the two poles.
The Amazon Basic in the attic will do better on all north and south channels together than the Clearstream 4. That is unless you remove the reflector from the Clearstream.
Funny that my amazon antenna theoretically can get me a more consistent signal than my clear stream. I may buy another one , heck they are 17 bucks and plug it in in my attic with the preamp ? And see how well it does.
I would agree that the antenna is pointed at the core of that green.
RCA has multiple preamps - I was asking really was it specifically the RCA TVPRAMP1Z which has overload prevention capabilities.
Is the Clearstream pointed directly 30 degrees? It is a directional antenna that has to be pointed specifically at a set of channels in one direction. The Amazon Basic is multi-directional and does not have to be pointed specifically at any channels.
If the Clearstream has a preamp on it that overloads the tuner, it will underperform the Amazon Basic. I would try the Clearstream without the preamp pointed at 30 degrees using a compass.
Putting the Amazon Basic in the attic with the preamp would get you both north and south channels. However the preamp has to be a good one like the RCA TVPRAMP1Z. Non-quality preamps may just hinder reception given their higher noise factor.
I definitely would have another go at the C4 - it is a great antenna. Point it at 35 degrees. As MarkKindle said, “without the preamp.” When a TVFool report shows an NM in the high 50’s, that is a very strong signal that shouldn’t require an amp.
The Amazon basic may do well in the attic also without an amp. Try it also in the attic. My guess is that the Amazon Basic would get you all the channels in green and yellow both north and south. If not, then try it with a good preamp - not just any preamp because as MarkKindle said, a poor preamp will only hinder reception by adding noise to the line. The RCA TVPRAMP1Z is a good one and inexpensive.
With an attic antenna you should be getting at least 30 channels (not counting sub-channels). If you split the signal multiple ways from the antenna to multiple receivers\TVs, then a distribution amp may be needed.
