Digital Antenna Distribution

My intent is to clear up any and all miss information regarding Off Air digital HD Whole house audio structural wiring. I will also address installation tips, trouble shooting suggestions, you name it and we will discuss it. Anything that is pushed through a wire or wireless we will clear up any and wrong information that the public has been led to believe. You may have been advised by a local store or a tech on a phone, which seems to be were the problem, is! Wrong information!

    I was told that I need 2GHz Splitters for Digital Antenna,is this true ?

    You don’t need 2GHz splitters or Amplifiers for your Local off-Air Digital Frequencies. Most Off-Air Digital HD is UHF 55.25 to 885.25 MHz though there is some States that do broadcast in VHF. The VHF will be sold off eventually in my opinion. Regardless how the signal is sent to your antenna the frequency of this Digital signal remains the standard 55 to 885.25MHz. We will still utilize the standard frequency splitters and amplifiers to distribute the digital off-air antenna and CATV as well. You can upgrade if the distribution products have seen better days, 5 to 1000MHz is the frequency your splitters & amplifiers should be for CATV,though the 5MHz for Antenna is not needed,most all RF splitters and amplifiers are 5 to 1GHz anyway. Antenna does not require the 5MHz to 44MHz,this is only for CATV return path, pay-per-view and other communication back to the CATV company.

    I was told that digital antena is going to be 3-4GHZ, so you can combine it with cable and satilight dishes still. Is this the case?
    Also, I want to distribute 35 modulated channels to an apartment complex, and the cable company, cox said they cannot help me. Does Automatemyhome sell 35 channel modulaters? I figure I can combine it at the head end, and no one will know the difference, even if the cable company won’t help me.

    Hi Rick,
    ATSC or Digital Antenna will transmit in the UHF range of 471.25 to
    885.25 Max. There is still a few broadcasters using VHF though eventually
    the VHF may be sold off. Combining Ant, CATV, and Satellite on one coax
    is not going to happen this week. DirecTV has the new SWM Switches that will allow
    Diplexing though only with one port passing Diplexers & splitters, the first generation
    Diplexers will not work due to the power passing and Frequency. Basically 2MHz to 2150MHz,
    the low end is the data.
    The 35 modulated channel is basically a small CATV system on it’s own .The CATV companies
    back in the day assisted MDU/Apt’s with modulation of security cameras and still do in certain
    areas. The 35 channels of modulation would definitely take food off the CATV companies plate.
    The most important issue is hard line vs. drop cable, hard line now up to 90v,you simply
    Cannot take apart the front end of the system as you would with RG6. Hey you can always
    dedicate a 2nd RG6 coax and create your own system! Keep in mind the
    Residential modulators
    have side bands and are great for smaller systems such as residential, bars, restaurant
    applications though you must be at least two channels apart. The more expensive modulators
    have “saw filtering” no side bands much like the CATV companies that modulate the analog channels.
