    I never claimed it didn't. It's just one more stupid thing the
    government burdens the people with.

    Not really. This refers to the radio signal's ability to bend to follow
    the curvature of the earth, and nothing more or less. Lower frequencies
    will bend as they propagate, which is why communication with submarines
    was historically made with very low frequencies, (now satellite) and why
    high frequencies are used for short terrestrial distances. Under this
    principle, UHF frequencies and higher are considered as line of sight.

    They are clearly line of sight. There is absolutely no question about
    that fact. Signal reflection does not change that physical principle.

    >> which can give coverage inside buildings.

    >
    > That isnt the reason for coverage inside buildings.


    Yes it is. There is significant loss when signals penetrate buildings,
    particularly on lower floors of high rises in congested areas. The
    reason you can recieve a signal at all in some cases is that it comes
    through the windows, often reflected off of other objects.

    Nope, that works because those very low frequencys
    penetrate the water, different effect entirely.

    Wrong again.

    Only by pig ignorant fools like you.

    I'm nothing like line of sight from the GSM base I use in my house, and it works fine anyway.

    >>> There is some bouncing,


    >> So its clearly not line of sight.

    It aint line of sight when its a reflected signal.

    > Signal reflection does not change that physical principle.


    It does mean that its not line of sight tho.

    Pity those arent usually line of sight of the base
    and it doesnt work due to the reflections either.

    Unless your house is farther away than the horizon, it most
    certainly is "line of sight" in this sense.


    > It aint line of sight when its a reflected signal.


    Signals "reflected" by local structures are MUCH less
    of a contributor to good performance than is commonly
    thought; they are, in fact, generally a detriment (see
    "multipath interference" for more).

    And YOU'VE been doing RF engineering work for
    how long, exactly?

    Nope. The base is on a hill at the back of town, and I am
    on the flat below the hill, with the base well over the top
    of the hill from my house. Its nothing like line of sight.

    Let's put it this way - how, *exactly*, do YOU
    believe that the signals are getting from you to
    your base at the house, in the above scenario?

    So, you would have no problem with someone turning on a PED which could
    cause a full scale change in the glideslope indication (full up to full
    down) while the aircraft is doing an approach to minimums?

    I've actually observed this when I did a simple experiment using parked
    aircraft. Some aircraft, there was no effect. In others there was. Worst
    case was the full scale reversal on the glideslope indicator. Another case
    the localizer went from full scale left to two dots right.

    Care to tell us what the effect of either would be on an approach to
    minimums. What would the effect be of the errant down glideslope
    indication on an ILS CAT IIIB approach to 28R at KSFO?
