New Antenna

Finally got my dipole up on a 45' MFJ fiberglass pushup mast today. Nothing special, just a 130' dipole fed with 450 Ladderline straight into an old MFJ  986 Differential T Tuner. Tunes just fine 80 to 15 meters. And best of all, NO interference...........yet!

    James you are a lucky man! I still have massive peaks at 14.030 and other places. I need to find time to find them.

    Nice! Nothing like using the inverse square law to your advantage.

    Inverse square law. George?     Not sure what you mean here.    Jim    KD1I

    Power density of a signal is proportional to the inverse square of the distance from its source.

    Or, local QRM decreases by a factor of 4 when distance to it is doubled. Getting away from noise sources pays dividends very rapidly.

    Thanks for that George! Now the comment makes far more sense.

    Thanks, George. I am familiar with the inverse square law but not sure what you were referring to here regarding James antenna.    I thought you might be kidding him.   I'd have made reference to rattling the either myself.  HI HI    73, Jim

    Arrgh... this falls under the category of stuff I used to know but long forgot until I have to use it again at which time I become great friends with Google.

    I did! And you never came back to me! Of course, you may not have been on the air at the time I did transmit! :-)

    Thanks! It only took a couple of months to get things together and then get the time to put it all up. Still have a vertical I plan to put up as well.

    George, it helped a lot! I'm amazed that I have no "noticeable" interference from my neighbors electronics. Another benefit, I reconnected my Bose speakers and no spikes showing from the **** wall wart!

    How many guy lines does that mast require?
    Which model is it?

    The instructions suggest at least 2 sets of guys. It's fastened to the back of the house as well. I don't remember the model number. But, it is the 50' heavy duty model. Overall, it was easy to install. Just right for an inverted V. James WD5GWY
