    Concur also. Approximately 65-miles is the digital cliff, meaning the signal is being lost at that point via the curvature of the earth. Amplifying the signal will do nothing to help the situation as it will amplify the noise that harms the signal also.

    My experience in "deep fringe" areas like this (my grandparents lake house is 55mi from towers over rolling, tree filled terrain) is to get a high gain antenna, mount it as high as possible, make the coax run as short as possible to the tuner. Personally, I've had zero luck with pre-amps, they have only made things worse in my practice. Amplifying a signal that doesn't exist, amplifies nothing.

    The antenna you have shown is not very close, at all, to what is called for. And as stated earlier, the attic is convenient but not a good choice for the altitude neede. You might get on one of the Websites that will suggest the antenna requirements for coupling your location to the transmitting tower. Are your stations really broadcasting on the "old VHF" frequencies? You will get answers from such a Website

    The amp at the antenna should be a pre-amp. Just get a more powerful one. I use a 30 to 35dB pre-amp at my antenna. It's been working great for fourteen years.

    I use a Winegard pre-amp. I have no idea what the model is though. I remember buying two initially. One with something like a 15 to 20dB gain, and one with something like a 30 or 35dB gain. I couldn't get the channels in reliably with the lower gain one. But once I installed the higher gain pre-amp, it made a huge difference.

    Did you start or visit these sites first?

    TV Fool

    The gold standard for folks wanting to do long distance ota:
    Over-The-Air (OTA) Digital Television - Canadian TV, Computing and Home Theatre Forums
    and specifically:
    Rooftop antenna selection in Montreal NDG - Canadian TV, Computing and Home Theatre Forums
    for Montrealers. YMMV...

    Maybe here to see what your neighbors can do:

    AFAIK you can't combine amps to get "stronger" signals. Start with the best ant for your situation and install a quality pre-amp at the mast. You didn't indicate if you are splitting the signal for additional televisions. If so then a distribution amp inside at the splitter location to overcome signal loss from the splitting.

    Some types of pre-amps to read about:
    Pre-Amplifiers - Solid Signal
    Not recommending site - just FYI only.

    Additional ota educational information for consideration:

    HDTV Antenna Selection Guide, Reviews and Information
    Dual Antenna Boom
    The Antenna Forum [Archive] - WTFDA Forums
    Local HDTV Info and Reception - High Def Forum - Your High Definition Community & High Definition Resource

    Good luck and Godspeed

    That ClearStream 4 is a strong outdoor receiver that's actually multidirectional - I guess it's out of the question to increase elevation and put it on the roof?

    Attic installations can be tricky - you can lose up to 40-50% of your signal there. I don't know if your amp experiment worked, but as others have suggested you can easily get garbage in/garbage out.

    On the other hand, preamps are known to slightly improve TV reception from the attic, in which case you should keep them as close to the antenna as possible.

    Eh, maybe; @seadooxp3 never replied with any feedback on a solution, so it’s not certain they’re set. Just didn’t want you or anyone else adding feedback expecting the OP.
