Did they check the signal quality at the entrance? You shouldn't need amps with what little you have unless they're very long runs. Where is the splitter installed at the entrance?
As for the antenna is this an outdoor antenna? How do you know it's pointing correctly? An amp may help on the antenna. I have a $20 outdoor antenna I now use as a backup since I get those channels with my cable co. I never had any issues as long as it was pointing in the right direction.
I did replace all the splitters in the house, I'm using the ones that state they are for digital distribution. Not the 500-900 mhz stuff (not sure if I got that numbering correct, but you know what I mean).
I used at DigiMax (from the cable company) at the entrance, which is only inches inside my apartment, and the cable is boxed in the stairwell in building, and they have 4 ports per floor, one for each apartment on a floor.
The DigiMax is rated at 5mghz - 1ghz each side is -3.5db, it's tri-splitter as I mentioned in my original message.
On the cable box in diagnostic mode, there are errors.
They calm (cable) that I have too much power? Too high of a signal?
Doesn't make sense to me.
As far as the Master Antenna, because I'm in an apartment building, the antenna itself is on our roof (I live in a 15 story building, I live on the 4th floor). There is a amplifier in the basement (ground floor) that feeds up to each of the apartments with some kind of BNC wiring (it's really very thick), installed over 50 years ago when the building were built.
When we went digital, the replaced the antennas, repositioned them, and swapped out the old amplifiers.
I went to the office and they are going to try and find me an new wall plate, which is where I tap into the master antenna of the building.
When I mentioned I was having trouble with channel 4 (what it used to be) or I should say NBC, she said most residents were having trouble with NBC. Not sure if they are broadcasting from the same location as all the others.
When the World Trade buildings went down, not all of the broadcasters moved back to the Empire State Building (where it was before they built the original WTC). So it's kinda of hard to focus on multi-locations to receive reception.
I hope when the new WTC is rebuilt (seems it finally might be finished in 2 more years) they move the broadcasting back to one tower!
I'm wondering if it could just be the cable box itself, not able to handle the data compression that they are using.
Yes, I am willing to pull out the wiring that I just installed. It is all running through a molding, so all of these wires, are very close together. There are 2 cables in RG6, one for cable tv, the other for regular over the air tv, then there is a door bell that is located in my bedroom that I used old telephone wiring to hook it up with, which is a 12volt system. Probably doesn't do anything, since it only sends a signal when someone pushes the doorbell.
The other is 2 CAT 5 network wiring.
Lastly, there is about 3 wireless routers through out my house. And 2 6.0 cordless phone systems.
So when I read about outside interference, I figured upgrading to Quad wiring was the better way to go in the long run, to run out anything causing any inference in my reception on TV.
