    Hey guys,

    Just wondering if using an 800 Watt rated end fed antenna with an KX2 10 Watts would have any effects on transmitting?

    If not why would they even offer Antennas with 30 Watts, 300 Watts, you would think everyone would just buy the 800 watt antenna to be on the safe side or to upgrade power down the road?

    The "800 watt" rated antenna will be slightly more efficient than the lower power rated models, so it should work better than they would.

    The reason "lower power" rated antennas are manufactured and sold is because it costs less to make them (less expensive materials) and for low power-only operators, they can save some money. They're also generally a bit "lighter" because the matching network components are smaller and weigh less -- could be a factor when backpacking and such.

    It costs almost nothing for salesmen to build these antennas.

    The real marketing happens when you find out you bought half of an antenna.

    Now he will try and sell you the following, in no particular order,


    Another type of balun

    "Antenna tuner"

    "Counterpoise" kit

    Vswr meter (he'll tell you the one in your rig is no good)

    Antenna analyzer (when the new vswr meter dies not exactly agree with the rig)

    Another balun, ER, "line isolator"

    Just a little good natured ribbing, Dave. Rege just has this "thing" about end feds and "half an antenna" and the image of a stuck record jumped into my head. No harm intended, all in good fun.
