    Some people get a regular antenna and a separate booster so the booster can be replaced if necessary.

    weathered aluminum loses conductivity,as do RCA connections in audio hardware,,home devices with av connectors,ditto,cleaner spray ( non reside type) may restore a good pic & quality signal

    choosing the installing point on the roof is IMPORTANT.

    a FREE path between the antenna and the tower.

    an indoor antenna is unstable because it uses INDIRECT (reflected) signal that differs when someone walks in the room or a vehicle passes on the street..

      i think you antenna sees the tower through a window.
      if yes and it has aluminum blinds .. check drawn blinds

    Yes, especially if you bend them often. I think its time to upgrade to cable

    Antennas are made of aluminium and plastic.

    Aluminium corrodes.

    Both it and plastic get dirty,

    and both of those conditions can cause signal loss.

    Out in the desert, an antenna will often last decades

    because there is little moisture to prompt corrosion.

    In a high-humidity environment, an antenna will often last only three to five years.

    Salty fog, as we get here on the central coast of California,

    accelerates all forms of antenna deterioration.

    Antennas cannot "be" digital, but they can of course receive digital signals.

    Just call it a TV antenna and no one will complain.

    Yes. It could go bad with anything from a bad coaxial wire running from the antenna to the TV, to the electronics in the signal amplifier going bad, to the power supply running the amplifier going bad. Even the contacts on the coax cable or in the TV's antenna jack can get oxidation and degrade the signal. There are a lot of things that can go wrong in electronics, but that's what you get when you buy crap from China (as if there are many alternatives).

    Most antennas come with boosters that do go bad eventually. Otherwise it's possible some local radio interference was introduced that the old antenna wasn't built to handle.
